Safety Information
The following conventions are used to indicate precautions in this document. Failure to heed
precautions provided in this document can result in serious or possibly even fatal injury or damage to
the products or to related equipment and systems.
Failure to heed a precaution classified as a caution can result inserious consequences depending
on the situation.
Precautions for UL/cUL Marking
•Do not connect or disconnect wiring, or perform signal checks while the power supply is turned
ON.
• The Inverter internal capacitor is still charged even after the power supply is turned OFF.
To prevent electric shock, disconnect all power before servicing the Inverter, and then wait at least
one minute after the power supply is disconnected.
Confirm that all indicators are OFF before proceeding.
• Do not perform a withstand voltage test on any part of the Inverter.
The Inverter is an electronic device that uses semiconductors, and is thus vulnerable to high
voltage.
• Do not remove the Digital Operator or the blank cover unless the power supply is turned OFF.
Never touch the printed circuit board (PCB) while the power supply is turned ON.
• This Inverter is not suitable for use on a circuit capable of delivering more than 18,000RMS
symmetrical amperes, 250 volts maximum (200V class Inverters) or 480 volts maximum(400V
class Inverters).
General Precautions
• Some drawings in this manual are shown with protective covers or shields removed in
order to show detail with more clarity. Make sure all covers and shields are replaced
before operating the product.
• This manual may be modified when necessary because of improvements to the product,
modifications, or changes in specifications.
• To order a copy of this manual, or if your copy has been damaged or lost , contact your
OMRON YASKAWA Motion Control B. V.
(Hereinafter called the OYMC) representatives.
• OYMC is not responsible for any modification of the product made by the user, since that
will void the guarantee.
WARNING
Indicates precautions that, if not heeded, could possibly result
in loss of life or serious injury.
CAUTION
Indicates precautions that, if not heeded,could result in
relatively serious or minor injury, damage to the product, or
faulty operation.

Precautions for CE Markings
• Only basic insulation to meet the requirements of protection class I and over voltage category II is
provided with control circuit terminals.
Additional insulation may be necessary in the end product to conform to CE requirements.
• For 400 V class Inverters, make sure to ground the supply neutral to conform to CE requirements.
• For conformance to EMC directives, refer to section 3 in this document. For details, refer to the
following document: Document No. EZZ008390 for English version
Receiving
Mounting
CAUTION
Use 75 C copper wires or equivalent.
Low voltage wires shall be wired with Class I Wiring.
CAUTION
• Do not install or operate any Inverter That is damaged or has missing parts.
Failure to observe this caution may result in injury or equipment damage.
CAUTION
• Lift the Inverter by the heatsink. When moving the Inverter, never lift it by the
plastic case or the terminal covers.
Otherwise, the main unit may fall and be damaged.
• Mount the Inverter on nonflammable material (i.e., metal).
Failure to observe this caution may result in a fire.
• When mounting Inverters in an enclosure, install a fan or other cooling device to
keep the intake air temperature below 122°F (45°C) for IP20 (open chassis type),
or below 105°F(40°C) for NEMA1 (TYPE1).
Overheating may cause a fire or damage the Inverter.
• The VS-V7AZ generates heat. For effective cooling, mount it vertically.
Refer to the figure in Mounting Dimensions on section 3.

5. Start up Steps
The following seven steps describe the recommended minimum
operations to allow the V7 to control a connected motor in typical
configuration, to allow simple operation in the quickest time:
Step 1 – initial checks
1-1) Checkpoints before connecting the power supply.
Check the power supply if it is of the correct voltage.
CIMR-V7AZA2****: Three phase 200 to 230VAC
CIMR-V7AZB****: Single phase 200 to 240VAC (Wire R/L1 and S/L2)
CIMR-V7AZA4****: Three phase 380 to 460VAC
1-2) Make sure that the motor output terminals (U/T1, V/T2, W/T3) are connected to the
motor.
1-3) Ensure that the control circuit terminals and the control device are wired correctly.
1-4) Make sure that all control terminals are turned off.
1-5) Set the motor to no-load status (i.e. not connected to the mechanical system)
Step 2 – Connecting the power supply and check the display
status
1-1) After conducting the checks in step-1, connect the power supply.
1-2) If the display is normal when the power is connected it will read as follows;
RUN indicator: flashes
ALARM indicator: off
Setting/monitor indicators: FREF, FOUT or IOUT is lit.
Data display: displays the corresponding data for the indicator that is lit.
When fault has occurred, the details of the fault will be displayed. In that case, refer to
user’s manual and take necessary action.

19
Step 3 – Initializing parameters
To initialize the drive parameters to factory defaults, set parameter n001 = 12.
This will set the V7 to accept start/stop commands in what in termed “2-wire control”, i.e. 1
wire for a motor forward/stop command, and 1 wire for a motor reverse/stop command.
Step 4 – Set the motor rated current
This parameter is used for the electronic thermal function for motor overload detection (OL1). By correctly
setting this, the V7 will protect an overloaded motor from burning out.
Read the rated current (in amps) on the motor nameplate, and enter this into parameter n036. The example
to the below shows entering a value of 1.8Amps.

Explanation
Power On
Press the Mode Key repeatedly until the PRGM
indicator is lit.
Press the Enter Key. The data of n001 will be displayed.
Use the Increment or Decrement Key to set n001 to 12.
The display will be lit.
Press the Enter Key so that the set value will be entered
and the data display will be lit.
In approx.
1 s.
The parameter number will be displayed.

Press the Enter Key. The data of n036 will be displayed.
Use the Increment or Decrement Key to set the rated
motor current. The display will flash.
Press the Enter Key so that the set value will be entered
and the data display will be lit.
In approx.
1 s.
The parameter number will be displayed.

20
Step 5 – Set the motor rated frequency
This is the maximum frequency the motor can run and allows the V7 to properly control the
motor.
Read the rated frequency (in Hz) on the motor nameplate, and enter this into parameters
n011.
Step 6 – Set the operation command
This is the method for motor run and stop commands (i.e. how the inverter will start and
stop the motor). The two basic operations are for the RUN and STOP/RESET keys on the
Digital Operator, or for one of multi-function inputs through the control circuit terminals.
To set the operation command, enter the appropriate value into parameter n003:
0 = RUN and STOP/RESET keys on the Digital Operator are enabled.
1 = Multi-function inputs through the control circuit terminals.
The diagram to the below shows how to connect a switch to start/stop the motor in the
forward direction in “2-wire control”. Set parameter n003=1. To enable a separate switch for
reverse rotation on control terminal S2, set parameter n051=2, parameter n050=1 (This is
actually the factory default setting for n051 and n050).
