◆
The capacitor or surge absorber cannot be connected to the output side of the AC drive. Otherwise,
it may cause frequent AC drive fault or even damage the AC drive.
If the motor cable is too long, electrical resonance will be generated due to the impact of distributed
capacitance. This will damage the motor insulation or generate higher leakage current, causing the AC
drive to trip in overcurrent protection. If the motor cable is greater than 100 m long, an AC output
reactor must be installed close to the AC drive.

This terminal must be reliably connected to the main earthing conductor. Otherwise, it may cause
electric shock, mal-function or even damage to the AC drive.
◆
Do not connect the earthing terminal to the neutral conductor of the power supply.

circuit
P24 V power supply to
external unit.
Generally, it provides power supply to
DI/Do terminals and external sensors.
Maximum output current: 200 mA

supply
Connect to +24 V by default.
When DI1-DI7 need to be driven by
external signal, PLC needs to be
connected to external power supply
and be disconnected from +24 V.
