Issue:
What is the acceptable input voltage for an S-flex system?

Product Line:
ATV21 and ATV212 enclosed S-flex systems.

Environment:
All models, All serial numbers.

Cause:
Voltage fluctuations at customer site.

Resolution:
The input voltage tolerance is -15% / +10% of the rating of the drive.  Note that this is the acceptable range of the equipment but may not be acceptable in your application.   As input voltage drops, motor current will increase proportionally and it is possible for the motor current to increase to a point that a motor overload condition occurs while above the minimum voltage.
