Curious to learn the controls community's experience with the Square D Altivar 66 Drive. Please respond with your past drive history - good or bad. Please note the firmware version.
Situation:
Customer has reported a problem with several ATV66U41N4 drives while cycling power during routine maintenance. Proper shutdown procedures are being followed, however, the drive will produce a CL1 (Current Limit) fault which will not clear after power is cycled again. Drives with a firmware revision less than V3.0 were replaced with V3.2 but the problem still happens.
