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.
 
I'm sorry you are having difficulties with the ATV66 drive. We would like to assist you in resolving this issue but we need to know more about the application and the fault that is being displayed. Please contact the Square D Drives Product Support Group by calling 888-SQUARED.
