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:

• Input overvoltage

• DC bus overvoltage

• External fault

• Serial link fault

• Loss of 4–20 mA follower

• Motor phase loss

• Motor overload (after the thermal state has decreased below 100%)

• Drive controller overheating (when the thermal state has decreased

below 70%)

• Motor overheating (when the thermal sensor resistance is less than 1500

ohms)

• 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 of 30 s. If the drive controller remains faulted after 6 attempts, the fault

relay de-energizes and the drive controller must be reset by cycling power.

AUTOMATIC RESTART

• Automatic restart can only be used for machines or installations

that present no danger in the event of automatic restarting, either

for personnel or equipment.

• Equipment operation must conform with national and local safety

regulations.

Failure to follow these instructions can result in death, serious

injury, or equipment damage.
