Dear friend,
The wire connection and the setting for the inverter are following:
Regarding the wire connection, please connect "R" and "T" (at the inverter) to the shingle phase power supply (actraully, connect "R" and "S" or "S" and "T" both are ok.)
If you use it as three phase input, then please connect the three phase power supply to "R, S T". "U, V, W " connect to the motor .
If you use this VFD for this spindle motor 0-400HZ , Please set the parameters of the VFD as our following suggestion step by step, and don't change the sequence:
Step 1: Set PD005 =400
Step 2: Set PD004 =400
Step 3: Set PD003 =400
Step 4: Set PD072 =400
PD144=3000
As the orginal factory value setting is for a normal 50HZmotor, so please change the the above parameters according to your motor.

If there have any other questions please feel free to contact with us.


Have a good day.
