Procedure

1. Installation and Mounting
Install the Inverter according to the installation conditions. Refer to page 2-2. Ensure that the instal-
lation conditions are met.
2. Wiring and Connection
Connect to the power supply and peripheral devices. Refer to page 2-11. Select peripheral devices
which meet the specifications and wire correctly.
3. Power Connection
Carrying out the following pre-connection checks before turning on the power supply:
H Always ensure that a power supply of the correct voltage is used and that the power input terminal
(L1, L2, L3) is wired correctly.
200-V class: 3-phase 200 to 230 VDC, 50/60 Hz
400-V class: 3-phase 380 to 460 VDC, 50/60 Hz
H Make sure that the Motor output terminal (T1, T2, T3) and the Motor are connected correctly.
H Ensure that the control circuit terminals and the control device are wired correctly. Make sure that
all control terminals are turned OFF.
H When using a PG Speed Control Card, ensure that it is wired correctly.
H Set the motor to no-load status, (not connected to the mechanical system).
H 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.
H If the display at the time the power is connected is normal, it will read as follows:
Data Display: Frequency Ref
H When an fault has occurred, the details of the fault will be displayed. In that case, refer to Section 8
Maintenance Operations .
5. Initializing Parameters
Initialize the parameters.
6. Setting the Input Voltage
Set the Inverter input voltage (E1-01) to the correct voltage. (At the same time, set the short pin for
the 400-V class models of 18.5 KW or larger.)
7. Auto-tuning
Execute auto-tuning in the open-loop vector control mode.
H When auto-tuning is executed, motor parameters are set automatically.
H When this is not possible using auto-tuning, switch to V/f control mode and set the V/f pattern.
8. No-load Operation
Start the no-load motor using the Digital Operator.
H Set the frequency reference using the Digital Operator and start the motor using key sequences.
9. Actual Load Operation
Connect the mechanical system and operate using the Digital Operator.
H When there are no difficulties using the no-load operation, connect the mechanical system to the
motor and operate using the Digital Operator.
