Auto Restart Atr

This function allows an

automatic restart of the drive

controller if the cause of the fault

has disappeared and a run

command is maintained.

Yes - No No

An automatic restart is possible after the following faults:

• OSF Input line overvoltage

• ObF overbraking

• OtF motor overheating (when the thermal sensor

resistance is less than 1500 ohms)

• LFF loss of 4–20 mA

• OLF motor overload (after the thermal state has

decreased below 100%)

• OPF motor phase loss

• OHF drive overheating (when the thermal state has

decreased below 70%)

• SLF loss of RS-485 port communication

• EPF external fault

• CnF network communication fault

When the Auto restart is active, the fault relay remains

energized. If the fault has disappeared, the drive controller

will attempt to restart the motor after a delay time set by

parameter tAr. If the drive controller remains faulted after

attempting the number of restarts set in the parameter nAr,

the fault relay de-energizes and the drive controller must

be reset by cycling power.

★

This parameter is only available on 125–500 hp drive controllers.
