4.2.2. AMC circuit board
The AMC circuit board is the major component of the drive’s control system and
performs general drive control, motor control, and closed loop functions. The main
internal control devices and the peripheral input and output interfaces to the
customer communicate with the AMC circuit board via optical fibers.
The circuit board is fitted with a Motorola DSP processor and features two PPCS
and eight DDCS communication channels. These communication channels are used
for high-speed data transfer via the INT circuit board to the inverter.

4.2.2.1. Control tasks
The AMC circuit board has specific control and closed-loop tasks assigned to it. It
processes drive and status information, performs the speed and torque control
tasks, and monitors the operation of the drive.
All relevant drive variables (eg, speed, torque, current, voltage) are continuously
monitored by the control system. Pre-programmed protection functions ensure
that these variables remain within certain limits in order to maintain safe
operation of the drive. These internal functions are not programmable by the user.
Optionally, the AMC circuit board can monitor signals from external equipment.
These can be activated and adjusted with parameters.
Other general control, protection and monitoring tasks regarding the whole drive
include control and monitoring of:
–
Main circuit breaker protection device
–
–
1) AMC circuit board
2) Interface circuit board (INT)
