Trial Operation Procedures; Setting The Power Supply Voltage Jumper (380-480V Class Drives Of 4055 Or Higher); Power On - YASKAWA G7 Series Technical Manual

Trial Operation Procedures

The procedure for the trial operate is described in order in this section.
Setting the Power Supply Voltage Jumper (380-480 V Class Drives of 55
kW or Higher)
Set the power supply voltage jumper after setting E1-01 (Input Voltage Setting) for 380-480 V Class Drives
of 55 kW or higher. Insert the jumper into the voltage connector nearest to the actual power supply
voltage.
The jumper is factory-set to 440 V when shipped. If the power supply voltage is not 440 V, use the
following procedure to change the setting.
1. Turn OFF the power supply and wait for at least 5 minutes.
2. Confirm that the CHARGE indicator has gone out.
3. Remove the terminal cover.
4. Insert the jumper at the position for the voltage supplied to the Drive (see Fig 4.2).
5. Return the terminal cover to its original position.
200-240 V class power supply
380-480V class power supply

Power ON

Confirm all of the following items and then turn ON the power supply.
Check that the power supply is of the correct voltage.
•
200-240 V class: 3-phase 200 to 240 Vdc, 50/60Hz
380-480 V class: 3-phase 380 to 480 Vdc, 50/60Hz
Make sure that the motor output terminals (U/T1, V/T2, W/T3) and the motor are connected correctly.
•
Make sure that the Drive control circuit terminal and the control device are wired correctly.
•
Set all Drive control circuit terminals to OFF.
•
When using a PG Speed Control Card, make sure that it is wired correctly.
•
Make sure that the motor is not connected to the mechanical system (no-load status)
