motor.
 P1020 “Motor thermal load capacity” is the thermal load ability of the motor. When speed
is rated, P1020 is in relation to the point where the motor operates at P1020 of rated
motor current with rated temperature rise.
 P1022 “Motor insulation grade” represents different permissible motor temperature and
different permissible temperature rise under different ambient temperature, which refers
to NEMA MG1. If the reference standard of motor is different, setting values of P1023
and P1024 should be modified. Motor temperature threshold and temperature rise
threshold are adjusted by P1023 and P1024 internally.

When calculated temperature or temperature rise is higher than the threshold, electronic
motor thermal protection fault is generated.


In SVC/SLVC mode, when motor speed is less than speed threshold of motor
stall(P0572), current reference speed is larger than P0572, and output torque is limited
by maximum torque, motor stall fault is generated.


In SVC/SLVC mode, if motor speed is negative and motor rotation direction(P0013) is 0,
or motor speed is positive and P0013 is 1, motor reverse fault is generated.
