Does ATV630 support constant torque applications which require a significant overload (up to 150%)?

Altivar Process variable speed drives are designed for use in two operating modes that can optimize the drive nominal rating according to the system constraints.

These two modes are:

  • Normal duty (ND):
Dedicated mode for applications requiring a slight overload (up to 110%) with a motor power no higher than the drive nominal power.
The drive is designed to run up to 60 s at 110% of nominal current.
  • Heavy duty (HD):
Dedicated mode for applications requiring a significant overload (up to 150%) with a motor power no higher than the drive nominal power derated by one rating.
The drive is designed to run up to 60 s at 150% of nominal current.
