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.
