3.2.3 AMC circuit board
Overview
The AMC circuit board is the major component of
the control system of the drive and performs gen-
eral drive, motor control, and closed loop func-
tions. The main internal control devices and the
peripheral input and output interfaces to the cus-
tomer communicate with the AMC circuit board via
optical fibers.
The circuit board is fitted with a Motorola DSP pro-
cessor and features two PPCS and eight DDCS
communication channels. The communication
channels are used for high speed data transfer via
the INT circuit boards to the Phase-INT circuit
boards inside the phase modules.
AFE and INU have their own AMC circuit board
