21.9 FAULTS AND ALARMS
When the control mode is PM with encoder (P0202 = 6), fault reset will only be accepted with stopped motor.
Except for the F079 (Encoder fault) reset, which could occur with the motor shaft in movement; however, the
motor must be stopped in order to avoid operation problems after the fault reset.

Description:
It indicates the torque developed by the motor, as a percentage of the motor rated current (P0401). By using the
analog output AO1 or AO2 (modulus), AO3 or AO4 programmed to show the torque current reference (Iq*), the
motor torque can be calculated through the following formula:
T
motor
= {Iq* x P0401 x 20 [%]} / I
HD
Where:
Iq * in (Volts).
I
HD
is the inverter HD current (P0295).
