Trial Operation Procedures; Application Confirmation; Setting The Power Supply Voltage Jumper (400 V Class Inverters Of 75 Kw Or Higher); Power On - YASKAWA CIMR-F7A Instruction Manual

Trial Operation Procedures

The procedure for the trial operate is described in order in this section.

Application Confirmation

First, confirm the application before using the Inverter.
Fan, blower, pump
•
Other equipment
•
For any Inverter application other than a fan, blower, or pump, set C6-01 (CT/VT Selection) to 0 (CT: low car-
rier, constant torque). The default setting is 1 (VT: high carrier, variable torque) for Inverters with SPEC: C or
earlier and 0 (CT: low carrier, constant torque) for Inverters with SPEC: E or later.
However, only 1(VT) can be set for 200 V Class 110 kW as well as 400 V Class 220 kW and 300 kW Inverters
with any SPEC.
Setting the Power Supply Voltage Jumper (400 V Class Inverters of 75 kW
or Higher)
Set the power supply voltage jumper after setting E1-01 (Input Voltage Setting) for 400 V Class Inverters
of 75 kW or higher. Insert the jumper into the power tap nearest to the actual power supply voltage. If the
wrong connector is selected, the Inverter may be damaged.
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 Inverter (see Fig 4.2).
5. Return the terminal cover to its original position.
200 V Class power supply
400V Class power supply

Power ON

Confirm all of the following items and then turn ON the power supply.
1. Check that the power supply is of the correct voltage.
200V Class: 3-phase 200 to 240 VAC 50/60 Hz
400V Class: 3-phase 380 to 480 VAC 50/60 Hz
For an Inverter of 200 V, 37 kW or more, use one of the following power supplies for the cooling fan.
3-phase 200/208/220 VAC 50 Hz or 3-phase 200/208/220/230 VAC 60 Hz
