Setting up an S100 with a Permanent Magnet Motor
Purpose
This application note shows the simple steps involved in setting up a permanent magnet (PM) motor on an S100 drive. All S100’s with firmware version 2.50 or greater support PM motor control.
Parameters
Setup
the parameters below. Note that some parameter settings are based on the motor
nameplate. The nameplate in this
document is only an example. It is
imperative to have access to the motor nameplate in order to program in the
