1. Commissioning procedures for closed-loop vector control of asynchronous motor
Step 1: Restore to default value via keypad
Step 2: Set P00.03, P00.04 and P02 group motor nameplate parameters
Step 3: Motor parameter autotuning
Carry out rotary parameter autotuning or static parameter autotuning via keypad, if the motor
can be disconnected from load, then it is users can carry out rotary parameter autotuning;
otherwise, carry out static parameter autotuning, the parameter obtained from autotuning will
be saved in P02 motor parameter group automatically.
Step 4: Verify whether the encoder is installed and set properly
a) Confirm the encoder direction and parameter setup
Set P20.01 (encoder pulse-per-revolution), set P00.00=2 and P00.10=20Hz, and run the VFD, at
this point, the motor rotates at 20Hz, observe whether the speed measurement value of P18.00
is correct, if the value is negative, it indicates the encoder direction is reversed, under such
situation, set P20.02 to 1; if the speed measurement value deviates greatly, it indicates P20.01 is
set improperly. Observe whether P18.02 (encoder Z pulse count value) fluctuates, if yes, it
indicates the encoder suffers interference or P20.01 is set improperly, requiring users to check
the wiring and the shielding layer.
b) Determine Z pulse direction
Set P00.10=20Hz, and set P00.13 (running direction) to forward and reverse direction
respectively to observe whether the difference value of P18.02 is less than 5, if the difference
value remains to be larger than 5 after setting Z pulse reversal function of P20.02, power off
and exchange phase A and phase B of the encoder, and then observe the difference between
the value of P18.02 during forward and reverse rotation. Z pulse direction only affects the
forward/reverse positioning precision of the spindle positioning carried out with Z pulse.
