Detection before
operation
(control power supply
provided)
Excessive stress should be avoided for the cable of the encoder.
During motor operation, notice whether the connecting cable
contacts the machine part, causing wear or dragging.
For the servo motor, contact the supplier for any vibration or loud
noise during operation.
Check the setting of each parameter for accuracy. Unexpected
movements might occur due to mechanical characteristics. Do not
make excessive adjustments to the parameter.
When resetting the parameter, check if the drive operates while the
servo is turned off (Servo Off), otherwise the drive would cause
malfunction.
When the relay operates, contact the supplier if no contact sound is
heard or there is any abnormal sound is generated.
Check if any abnormality occurs to the power indicator and LED
display.
5.2.
Power transmission for the drive
The user must follow the steps below.
I.
Check the relevant wiring between the motor and drive:
U, V, W and FG must be connected to red, white, black and green wires, respectively. If the
wiring is wrong, the motor operates abnormally. The earth wire FG of the motor must be
connected to the grounding protection terminal of the drive.
The encoder of the motor is connected to the CN2 correctly.
Warning: Do not connect the power supply end (R, S, T) to the output of the servo drive (U, V, W),
otherwise it may result in the damage of the servo drive.
II.
Connection for the power line of the drive: Connect the power supply to the drive. Refer to 3.1.3 for the
wiring of the power supply.
III.
Power on: For the power supply of the control circuit (L
1
, L
2
) and main circuit (R, S,T), the drive
shows the following when the power is turned on:
The digital inputs (DI6~DI8) of the factory setting are the CCW-limit (NL), CW-limit (PL) and emergency
stop (EMGS) signals. If the digital inputs (DI6~DI8) of the factory setting are not used, the setting of the
parameters PC-06~PC-08 of the digital inputs (DI) must be adjusted. Set the parameter to 0 (the function of
this DI disabled) or change it to other functional definitions.
