Warnings  
CAUTION  
Cables must not be connected or disconnected, nor signal tests carried out,  
while the power is switched on.  
The Varispeed F7 DC bus capacitor remains charged even after the power has been  
switched off. To avoid an electric shock hazard, disconnect the frequency inverter from the  
mains before carrying out maintenance. Then wait for at least 5 minutes after all LEDs  
have gone out.  
Do not perform a withstand voltage test on any part of the Varispeed. The frequency  
inverter contains semiconductors, which are not designed for such high voltages.  
Do not remove the digital operator while the mains supply is switched on. The printed cir-  
cuit board must also not be touched while the inverter is connected to the power.  
Never connect general LC/RC interference suppression filters, capacitors or overvoltage  
protection devices to the inverter input or output.  
To avoid unnecessary overcurrent faults, etc. being displayed, the signaling contacts of any  
contactor or switch fitted between inverter and motor must be integrated into the inverter  
control logic (e.g. baseblock).  
This is absolutely imperative!  
This manual must be read thoroughly before connecting and operating the inverter. All  
safety precautions and instructions for use must be followed.  
The inverter may must be operated with the appropriate line filters, following the installation  
instructions in this manual and with all covers closed and terminals covered.  
Only then will adequate protection be provided. Please do not connect or operate any  
equipment with visible damage or missing parts. The operating company is responsible  
for any injuries or equipment damage resulting from failure to heed the warnings in this  
manual.  
EN-2  
 
 
Safety Precautions and Instructions  
General  
Please read these safety precautions and instructions for use thoroughly before installing and oper-  
ating this inverter. Also read all of the warning signs on the inverter and ensure they are never dam-  
aged or removed.  
Live and hot inverter components may be accessible during operation. Removal of housing compo-  
nents, the digital operator or terminal covers runs the risk of serious injuries or damage in the event  
of incorrect installation or operation. The fact that frequency inverters control rotating mechanical  
machine components can give rise to other dangers.  
The instructions in this manual must be followed. Installation, operation and maintenance may only  
be carried out by qualified personnel. For the purposes of the safety precautions, qualified personnel  
are defined as individuals who are familiar with the installation, starting, operation and maintenance  
of frequency inverters and have the proper qualifications for this work. Safe operation of these units  
is only possible if they are used properly for their intended purpose.  
The DC bus capacitors can remain live for about 5 minutes after the inverter is disconnected from  
the power. It is therefore necessary to wait for this time before opening its covers. All of the main cir-  
cuit terminals may still carry dangerous voltages.  
Children and other unauthorized persons must not be allowed access to these inverters.  
Keep these Safety Precautions and Instructions for Use readily accessible and supply them to all  
persons with any form of access to the inverters.  
Intended Use  
Frequency inverters are intended for installation in electrical systems or machinery.  
Their installation in machinery and systems must conform to the following product standards of the  
Low Voltage Directive:  
EN 50178, 1997-10, Equipping of Power Systems with Electronic Devices  
EN 60204-1, 1997-12Machine Safety and Equipping with Electrical Devices  
Part 1: General Requirements (IEC 60204-1:1997)/  
Please note: Includes Corrigendum of September 1998  
EN 61010-1, A2, 1995Safety Requirements for Information Technology Equipment  
(IEC 950, 1991 + A1, 1992 + A2, 1993 + A3, 1995 + A4, 1996, modified)  
CE marking is carried out to EN 50178, using the line filters specified in this manual and following  
the appropriate installation instructions.  
Transportation and storage  
The instructions for transportation, storage and proper handling must be followed in accordance with  
the technical data.  
Installation  
Install and cool the inverters as specified in the documentation. The cooling air must flow in the  
specified direction. The inverter may therefore only be operated in the specified position (e.g.  
upright). Maintain the specified clearances. Protect the inverters against impermissible loads. Com-  
ponents must not be bent nor insulation clearances changed. To avoid damage being caused by  
static electricity, do not touch any electronic components or contacts.  
EN-3  
 
 
Electrical Connection  
Carry out any work on live equipment in compliance with the national safety and accident prevention  
regulations. Carry out electrical installation in compliance with the relevant regulations. In particular,  
follow the installation instructions ensuring electromagnetic compatibility (EMC), e.g. shielding,  
grounding, filter arrangement and laying of cables. This also applies to equipment with the CE mark.  
It is the responsibility of the manufacturer of the system or machine to ensure conformity with EMC  
limits.  
Your supplier or Omron Yaskawa Motion Control representative must be contacted when using leak-  
age current circuit breaker in conjunction with frequency inverters.  
In certain systems it may be necessary to use additional monitoring and safety devices in compli-  
ance with the relevant safety and accident prevention regulations. The frequency inverter hardware  
must not be modified.  
Notes  
The Varispeed F7 frequency inverters are certified to CE, UL, and cUL  
EMC Compatibility  
Introduction  
This manual was compiled to help system manufacturers using OMRON YASKAWA Motion Control  
(OYMC) frequency inverters design and install electrical switch gear. It also describes the measures  
necessary to comply with the EMC Directive. The manual's installation and wiring instructions must  
therefore be followed.  
Our products are tested by authorized bodies using the standards listed below.  
Product standard: EN 61800-3:1996  
EN 61800-3; A11:2000  
Measures to Ensure Conformity of OYMC Frequency inverters to the EMC Directive  
OYMC frequency inverters do not necessarily have to be installed in a switch cabinet.  
It is not possible to give detailed instructions for all of the possible types of installation. This manual  
therefore has to be limited to general guidelines.  
All electrical equipment produces radio and line-borne interference at various frequencies. The  
cables pass this on to the environment like an aerial.  
Connecting an item of electrical equipment (e.g. drive) to a supply without a line filter can therefore  
allow HF or LF interference to get into the mains.  
The basic countermeasures are isolation of the wiring of control and power components, proper  
grounding and shielding of cables.  
A large contact area is necessary for low-impedance grounding of HF interference. The use of  
grounding straps instead of cables is therefore definitely advisable.  
Moreover, cable shields must be connected with purpose-made ground clips.  
EN-4  
 
 
Laying Cables  
Measures Against Line-Borne Interference:  
Line filter and frequency inverter must be mounted on the same metal plate. Mount the two compo-  
nents as close to each other as possible, with cables kept as short as possible.  
Use a power cable with well-grounded shield. For motor cables up to 50 meters in length use  
shielded cables. Arrange all grounds so as to maximize the area of the end of the lead in contact  
with the ground terminal (e.g. metal plate).  
Shielded Cable:  
Use a cable with braided shield.  
Ground the maximum possible area of the shield. It is advisable to ground the shield by connect-  
ing the cable to the ground plate with metal clips (see following figure).  
Ground Plate  
Ground Clip  
Fig 1 Earthing the cable shield with metal clips  
The grounding surfaces must be highly conductive bare metal. Remove any coats of varnish and  
paint.  
– Ground the cable shields at both ends.  
– Ground the motor of the machine.

Installation  
Mechanical Installation  
Unpacking the Inverter  
Check the following items after unpacking the inverter.  
Item  
Method  
Has the correct Inverter model been  
delivered?  
Check the model number on the nameplate on the side of the  
Inverter.  
Inspect the entire exterior of the Inverter to see if there are any  
scratches or other damage resulting from shipping.  
Is the Inverter damaged in any way?  
Are any screws or other components  
loose?  
Use a screwdriver or other tools to check for tightness.  
If any irregularities in the above items are found, contact the agency from which the Inverter was pur-  
chased or your Omron Yaskawa Motion Control representative immediately.  
Checking the Installation Site  
Protection covers are attached to the top and bottom of the NEMA 1 / IP20 Inverters. Be sure to  
remove the top cover before operating a 200 or 400 V Class Inverter with a capacity of 18.5 kW or  
less inside a panel.  
Observe the following precautions when mounting the Inverter:  
Install the Inverter in a clean location which is free from oil mist and dust. It can be installed in a  
totally enclosed panel that is completely shielded from floating dust.  
When installing or operating the Inverter, always take special care so that metal powder, oil,  
water, or other foreign matter does enter the Inverter.  
Do not install the Inverter on combustible material, such as wood.  
Install the Inverter in a location free from radioactive materials and combustible materials.  
Install the Inverter in a location free from harmful gasses and liquids.  
Install the Inverter in a location without excessive oscillation.  
Install the Inverter in a location free from chlorides.  
Install the Inverter in a location without direct sunlight.

Consider the following precautions for the main circuit power supply input.  
If a moulded case circuit breaker is used for the power supply connection (R/L1, S/L2, and T/L3),  
ensure that the circuit breaker is suitable for the Inverter.  
EN-12  
 
 
If an earth leakage breaker is used, it should be able to detect all kinds of current in order to  
ensure a safe earth leakage current detection  
A magnetic contactor or other switching device can be used at the inverter input. The inverter  
should not be powered up more than once per hour.  
The input phases (R/S/T) can be connected in any sequence.  
If the Inverter is connected to a large-capacity power transformer (600 kW or more) or a phase  
advancing capacitor is switched nearby, an excessive peak current could flow through the input  
power circuit, causing an inverter damage. As a countermeasure install an optional AC Reactor  
at the inverter input or a DC reactor at the DC reactor connection terminals.  
Use a surge absorber or diode for inductive loads near the Inverter. Inductive loads include mag-  
netic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.  
Wiring the Output Side of the Main Circuit  
The following precautions should be considered for the output circuit wiring.  
Never connect any power source to the inverter output terminals. Otherwise the inverter can be  
damaged.  
Never short or ground the output terminals. Otherwise the inverter can be damaged.  
Do not use phase correction capacitors. Otherwise the inverter and capacitors can be damaged.  
Check the control sequence to make sure, that the magnetic contactor (MC) between the Inverter  
and motor is not turned ON or OFF during inverter operation. If the MC is turned ON during the  
Inverter is operation, a large inrush current will be created and the inverter’s overcurrent protec-  
tion may operate.  
Ground Connection  
The following precautions should be considered for the ground connection.  
Do not share the ground wire with other devices, such as welding machines or power tools.  
Always use a ground wire, that complies with technical standards on electrical equipment and  
minimize the length of the ground wire.  
Leakage current is caused by the Inverter. Therefore, if the distance between the ground elec-  
trode and the ground terminal is too long, potential on the ground terminal of the Inverter will  
become unstable.  
When more than one Inverter is used, do not to loop the ground wire.  
OK  
NO  
Fig 7 Ground Wiring  
Control Circuit Wiring Precautions  
Consider the following precautions for wiring the control circuits.  
Separate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1,  
V/T2, W/T3, B1, B2,  
,
1, 2, and 3, PO, NO) and other high-power lines.  
Separate wiring for control circuit terminals MA, MB, MC, M1 to M6 (relay outputs) from wiring to  
other control circuit terminals.  
If an optional external power supply is used, it should be a UL Listed Class 2 power supply.  
Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating faults.  
Ground the cable shields with the maximum contact area of the shield and ground.  
Cable shields have to be grounded on both cable ends.

Before Power Up  
The following points should be checked carefully before the power is switched on.  
Check if the power supply meets the inverter specification.  
Check if the power supply cables are tightly connected to the right terminals (L1, L2, L3).  
Check if the motor cables are tightly connected to the right terminals on the inverter side (U, V,  
W) as well as on the motor side.  
Check if the braking unit / braking resistor is connected correctly.  
Check if the Inverter control circuit terminal and the control device are wired correctly.  
Set all Inverter control circuit terminals to OFF.  
When a PG card is used, check if it is wired correctly.

Autotuning  
Autotuning sets motor parameters automatically when using Open Loop or Closed Loop Vector con-  
trol, when the cable length is long or the installation has changed.  
Setting the Autotuning Mode  
One of the following three autotuning modes can be set.  
Rotating autotuning  
Non-rotating autotuning  
Non-rotating autotuning for line-to-line resistance only  
Rotating Autotuning (T1-01 = 0)  
Rotating autotuning is used for Open Loop and Closed Loop Vector control only. Set T1-01 to 0,  
input the data from the motor nameplate, and then press the RUN key on the Digital Operator. The  
Inverter will operate the motor for approximately 1 minute and set the required motor parameters  
automatically.  
Non-rotating Autotuning (T1-01 = 1)  
Non-rotating autotuning is used for Open Loop and Closed Loop Vector control only. Set T1-01 to 1,  
input the data from the motor nameplate, and then press the RUN key on the Digital Operator. The  
inverter will supply power to the non-rotating motor for approximately 1 minute and some of the  
EN-16  
 
     
motor parameters will be set automatically. The remaining motor parameters will be set automati-  
cally during the first time operation.  
Non-rotating Autotuning for Line-to-Line Resistance (T1-01 = 2)  
Non-rotating autotuning for line-to-line resistance can be used in any control mode. This is the only  
possible autotuning for V/f control and V/f control with PG.  
It can be used to improve the performance when the motor cable is long, the cable length has  
changed or when the motor and inverter have different capacities.  
To perform autotuning in V/f control or V/f control with PG, set T1-02 (Motor rated power) and T1-04  
(Motor rated current) and then press the RUN key on the Digital Operator. The Inverter will supply  
power to the non-rotating motor for approximately 20 seconds and the Motor line-to-line resistance  
and cable resistance will be automatically measured.  
1. Power will be supplied to the motor during autotuning but the motor will not turn. Do not touch the motor  
until autotuning has been completed.  
2. Ensure that all motor contactors are closed before the autotuning is started.  
3. To cancel autotuning press the STOP key on the Digital Operator.

Troubleshooting  
General Faults and Alarms  
Faults and Alarms indicate unsusal inverter / application conditions.  
An alarm does not necessarily switch off the inverter but a message is displayed on the keypad (i.e.  
a flashing alarm code) and an alarm output can be generated at the multi-function outputs (H2-01  
and H2-02) if programmed. An alarm automatically disappears if the alarm condition is not present  
anymore.  
A fault switches the inverter output off immediately, a message is displayed on the keypad and the  
fault output is switched. The fault must be reset manually after the cause and the RUN signal have  
been removed.  
The following table shows a list of faults and alarms with their corrective actions.

Operator Programming Errors  
An Operator Programming Error (OPE) occurs when two or more parameter related to each other  
are set inappropriately or an individual parameter setting is incorrect. The Inverter does not operate  
until the parameter setting is corrected; however, no other alarm or fault output will occur. If an OPE  
occurs, change the related parameter by checking the cause shown in the table below. When an  
OPE error is displayed, press the ENTER key to see U1-34 (OPE Detected). This monitor displays
