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 r egulation. MCL inter facing is through a signal map. An operat or can
configure the signal ma p using either the Drive Diagnost ic Interface (keypad) or the
GE Control System Toolbox (see Figure 5-1).
Signals ar e either LAN or I/O-ba sed variables th at control the dr ive and provide
drive status feedback. For example, an analog input sign al provides speed reference.
This chapter describes the signal mapping, as follows:
