4-1
Procedure for Test Run
1.
Installation and Mounting
Install the Inverter according to the installation conditions. Refer to page 6.
Ensure that the installation conditions are met.
2.
Wiring and Connection
Connect to the power supply and peripheral devices. Refer to page 10.
Select peripheral devices which meet the specifications and wire correctly.
3.
Power Connection
Carry out the following pre-connection checks before turning on the power
supply.
• Always ensure that a power supply to the correct voltage is used and
that the power input terminals (R/L1, S/L2, and T/L3) are wired
correctly.
CIMR-J7AZ-2
_
: 3-phase 200 to 230 V AC
CIMR-J7AZ-B
_
: Single-phase 200 to 240 V AC (Wire R/L1 and S/L2)
CIMR-J7AZ-4
_
: 3-phase 380 to 460 V AC
• Make sure that the motor output terminals (U/T1, V/T2, and W/T3) are
connected to the motor correctly.
• Ensure that the control circuit terminals and the control device are
wired correctly. Make sure that all control terminals are turned off.
• Set the motor to no-load status (i.e., not connected to the mechanical
system).
• Having conducted the above checks, connect the power supply.
4.
Check the Display Status
Check to be sure that there are no faults in the Inverter.
• If the display at the time the power is connected is normal, 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 of the indicator that is lit.
• When a fault has occurred, the details of the fault will be displayed. In
that case, refer to Chapter 8 Maintenance Operations and take
necessary remedies.
5.
Initializing Parameters
Initialize the parameters.
• Set n01 to 8 for initialization in 2-wire sequence.
6.
Setting Parameters
Set the parameters required for a test run.
• Set the rated motor current in order to prevent the motor from burning
due to overloading.
7.
No-load Operation
Start the no-load motor using the Digital Operator.
• Set the frequency reference using the Digital Operator and start the
motor using key sequences.
8.
Actual Load Operation
Connect the mechanical system and operate using the Digital Operator.
• When ehere are no difficulties using the no-load operation, connect
the mechanical system to the motor and operate using the Digital
Operator.
