Amc Circuit Board; Control Tasks - ABB ACS5000 User Manual

3.4.2. AMC circuit board

The AMC circuit board is the major component of the drive's control system and performs
general drive, 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. 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.

3.4.2.1. 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 drive can monitor signals from external equipment. These can be activated and
adjusted with parameters (see Section 3.4.2.3, "Parameters", page 44).
Other general control, protection and monitoring tasks regarding the whole drive include
control and monitoring of:
– Main circuit breaker (MCB)
– Grounding switches
– Door interlocking
– Cooling system
