Grounding
The drive has a double supply circuit. If external power is lost, the supply switches to the auxiliary winding of the phase-shift trans-
former to output 1-phase power, and the drive can still operate normally. When the external power is restored, the supply switches
back to the external power.
Protection Requirements for the Supply Circuit
TT networks
: If the neutral point of the control power is directly grounded, connect the frame to the grounding terminal (the
grounding terminal has no connection with the neutral point grounding).
IT networks
: The neutral point of the control power is not directly grounded.
6.9.3 Control Circuit Wiring
The wiring terminals of the control circuit are as shown in table.
The digital input terminals must be passive nodes with a capacity of 1 A/24 V DC.
The digital output terminals provided by the system are passive nodes with a capacity of 5 A/220 V AC or 5 A/220 V DC.
The definitions of all the I/O terminals are defaults, and can be defined and configured again according to requirements.
