Inspection Item
Applicable?
1
The power input cables are connected to the R/L1, S, and
T/L2 terminals.
2
The motor input cables are connected to the U, V, and W
terminals.
3
The cross‑sectional area of the main circuit cables meets
the requirements.
4
The heat‑shrink tubes have been added to the cores of
main circuit cables, and the tubes completely cover the
cable conductors.
5
Confirm whether the motor output cables are longer
than 150 m (unshielded) or 50 m (shielded). If yes, reduce
the carrier frequency (F0‑15) and add an output reactor
(see the requirements for options).
6
The grounding cables are connected correctly.
7
The AC drive output terminals and control signal
terminals are securely connected.
8
The braking resistor and braking unit (if used) are
connected correctly and have proper resistance.
9
The control circuit cables are shielded twisted pairs
(STPs).
10
The optional cards are connected correctly.
11
If the AC drive is an STO model, confirm that the external
24 V power supply is connected properly.
