Will there be any issues if we connect either a 2 pole or a 4 pole motor to our ATV630 Drives?

Published date: 23 July 2019

Issue:
Will there be any issues if we connect either a 2 pole or a 4 pole motor to our Altivar Drives?

Product Line:
Altivar 630

Environment:
All

Cause:
Application inquiry.

Resolution:

No, just make sure Rated Motor Speed under the simply start menu matches the asynchronous RPM  listed on the motor nameplate. 
A 2 pole motor will have an RPM in the 3600 range.  A 4 pole will be in the 1800 range and an 8 pole will be in the 900 rpm range.
It's part of the basic programming.  NCR = Motor  rated current, NSP = Motor RPM
On the 212 drive it is F415 and F417, NCR and NSP on the 12, 312, 320 and 340, Motor Rated current and Motor Rated Speed on the Altivar 61/71 and Process drives.  Different name but same function.

We don't have to set the number of pole pairs, we just set the listed RPM on the motor and the drive will know how many pole pairs exist already.
