Signal Mapping | GE Medium Voltage GP Type G Drives, 2300 V instruction

Chapter 5 Signal Mapping

Introduction

The IS200DSPX Digital Signal Processor board (DSPX) contains and implements the drive’s control software. The DSPX is located in the drive’s control rack.

The drive software’s Motor Control Layer (MCL) performs motor control functions, such as current regulation. MCL interfacing is through a signal map. An operator can configure the signal map using either the Drive Diagnostic Interface (keypad) or the GE Control System Toolbox (see Figure 5-1).

Signals are either LAN or I/O-based variables that control the drive and provide drive status feedback. For example, an analog input signal provides speed reference.

This chapter describes the signal mapping, as follows:
