Step 3: Check electrical safety.
□√
No. Inspection Points
1
unbalance degree does not exceed 3%.
2
The total lead-in wire gauge and total switch capacity meet the
requirements.
3 There is no inter-phase or to-ground short circuit in the R, S, T power supply.
4
There is no inter-phase or to-ground short circuit in the U, V, W phases of the
controller. There is no to-ground short circuit in the U, V, W phases of the
motor.
5 There is no to-ground short circuit on the output side of the transformer.
6 There is no inter-phase or to-ground short circuit in the 220 V power supply.
7
The 24 V power supply has no short circuit between positive and negative or
to-ground short circuit.
8
The CANbus/Modbus communication cable has no short circuit with the 24
V power supply or short circuit to ground.
Step 4: Check the rotary encoder.
□√
No. Inspection Points
1 The encoder is installed reliably with correct wiring.
2
ducts to prevent interference.
3
The encoder cables are preferably directly connected to the control cabinet.
If the cable is not long enough and an extension cable is required, the
extension cable must be a shielded cable and preferably welded to the
original encoder cables by using the soldering iron.
4
The shield of the encoder cables is grounded on the end connected to the
controller (only one end is grounded to prevent interference).
