The ATV58 TRX drive is equipped with features that are designed to protect the drive controller and 
motor, and to provide process related information. Understanding the fault management capabilities of 
the drive controller and determining the proper configuration for the application can enhance the total 
system installation and performance over the life of the equipment. The fault messages provided by the 
drive controller can be divided into three categories:

• Protective faults are displayed when the drive detects conditions that may damage the drive controller 

and/or motor. The drive controller shuts down to prevent further damage from occurring.

• Drive faults are displayed when a problem in the drive needs to be diagnosed.

• Process faults are displayed when a process signal used by the drive controller is interrupted.

The fault relay (R1) provides 1 normally open and 1 normally closed contact. The relay is energized and 
the state of the contacts reverses when the drive controller is powered up and a fault is not present. This 
relay cannot be re-assigned.

The drive controller can be reset after a fault by one of three methods:

• Turning power to the drive controller off, wait for the LEDs to go off, and apply power.

• Using the reset button on the keypad, if programmed for local control, or by a logic input assigned to 

Fault Reset.

• By the Automatic Restart function if configured.

This function permits automatic restarting after the drive controller detects a fault, provided that the other 
operating functions are correct, a Run command is present, and the fault has disappeared. The factory 
setting for this function is NO. The number of restart attempts and the delay between these attempts is 
selectable. 

When the Auto restart is selected, the fault relay remains energized so that the drive controller does not 
signal a fault from a condition from which it may be able to restart. If the fault has disappeared, the drive 
controller will attempt to restart the motor after the delay time configured. The auto restart delay time is 
factory set at 30 seconds and has an adjustable range of 0.1 to 999.9 seconds. If the drive controller 
remains faulted after attempting the configured number of restarts, the fault relay will then deenergize. 
The drive controller must be reset by cycling power after the cause of the fault has been eliminated. The 
number of restart attempts is factory set at 5 and has an adjustable range of 0 to 255.
