Current limit value
With the startup modes "Current limiting" and "Voltage ramp + current limiting", the motor
current is limited to a maximum value during starting.
Note
At a rated operating current ≥ 9 A, the motor starter automatically reduces the current limit
value to 550%.

Messages and actions
Message
Action
Starting active The motor is switched on depending on the "Startup mode"
parameter.
Run-down active The motor is switched on depending on the "Run-down mode"
parameter.
No supply voltage ON command generates faults.
Current limiting active Motor starting current is limited.
