Issue:
How are the ATV32 and ATV320 set up for an automatic restart after a fault?

Product line:
Altivar 32 (ATV32)
Altivar 320 (ATV320)

Environment:
All models, all serial numbers   

Cause:
None  

Resolution:
This will NOT clear all faults. Safety-related faults must be cleared by power-cycling the drive. Lists of faults that can and cannot be cleared with Automatic Restart can be found in your drive's Programming Manual. 

DRI- > CONF > FULL > FLT- > ATR-
Navigate to the FLt menu and set parameter Atr to YES.
Only certain faults will permit an automatic restart.  If the condition that caused the fault clears, and the run command is still present, the drive will restart.  By default, the automatic restart will make multiple attempts to restart for 5 minutes before locking in fault.  Longer time periods are available per parameter tAr.

Note: This function requires tCC=2C and tCt=LEL or PFO (both parameters in the IO menu. It will not operate if the tCC=3C, or if control is managed by the keypad or serial communication network.
