Inverter limit
This function is a safety protection from the drive operation point. The function
checks for the following limits when the drive is running in the generating mode with
generating power greater than 10% of the motor nominal power and the speed
greater than 5% of the maximum speed. The limits checked are TORQUE
INVERTER CURRENT LIMIT and IPP OVERLOAD ALARM. If one of these limits is
hit, and a period of 200 ms elapses, the drive trips on the INV LIMIT fault, and the
brake is closed.
bit 4 indicates the current limit of the torque inverter.
