Appendix
5
With PowerFlex 523, you need to multiply the speed reference and divide the
speed feedback by a factor of 10.0 in order to get the correct value. Note that the
PowerFlex 4 and PowerFlex 5 drives have a different multiplier.
For example, if you set reference speed at 50, command speed is 50 Hz for
PowerFlex 4M and only 5 Hz for PowerFlex 523 and PowerFlex 525.
