ABB PPC902AE101 3BHE010751R0101 AMC Circuit Coard

Functional Description

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

control, and closed loop functions. The main internal control hardware 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 to the INT

circuit boards inside the ARU and INU.

The AMC circuit board has specific control and closed-loop tasks assigned to it. The tasks include processing

drive and status information, controlling the speed and torque, and monitoring the operation of the drive.

The AMC circuit board continuously monitors all relevant drive variables (eg, speed, torque, current, voltage).

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 offers monitoring of signals from external equipment. These can be activated and set

with parameters. Other general control, protection and monitoring tasks regarding the whole drive include

control and monitoring of:

• Main circuit breaker

• Grounding switch 

• Door locking system 

• Cooling system
