5.2 Trial Operation Procedures
5.2.1 Power ON
J Checkpoints before Turning ON the Power Supply
D Check that the power supply is of the correct voltage.
200 V class: 3-phase 200 to 230 VDC, 50/60 Hz
400 V class: 3-phase 380 to 460 VDC, 50/60 Hz
D
Make sure that the motor output terminals (U, V, W) and the motor are connected correctly.
D
Make sure that the Inverter control circuit terminal and the control device are wired correctly.
D
Set all Inverter control circuit terminals to OFF.
D
When using a PG Speed Control Card, make sure that it is wired correctly.
D
Make sure that the motor is not connected to the mechanical system (no-load status)
5.2.2 Checking the Display Status
If the Digital Operator’s display at the time the power is connected is normal, it will read as follows:
Frequency Ref
U1−01 = 0.00 HZ
[Normal]
The frequency reference monitor is
displayed in the data display section.
When an fault has occurred, the details of the fault will be displayed instead of the above display. In that
case, refer to Section 9 Maintenance Operations. The following display is an example of a fault display.
UV
Under Voltage
[Fault]
The display will differ depending
on the type of fault.
5.2.3 Initializing Constants
D
When replacing the controller PCB, check the Inverter capacity (kVA) in o2-04 first and then initialize
constants to the factory settings. There is no need to initialize constants the first time trial operation
is performed after purchasing the Inverter.
D
To initialize the constants, set “2220” in A1-03 (Initialize).
D
After initialization, the access level is set to Quick-start (A1-01). The following table shows the setting
method for Quick-start.
Use the following procedure to initialize constants.
