The AMC circuit board has specific control and closed-loop tasks assigned
to it.
The AMC circuit board processes drive and status information, performs
the speed and torque control tasks, and monitors 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 adjusted by parameter settings.
Other general control, protection and monitoring tasks regarding the
whole drive include control and monitoring of:
■ Main circuit breaker
■ Grounding switches
■ Door locking system
■ Cooling system
For further information on control, protection and monitoring functions, see
Signal and parameter table.
The control system is configured, customized and tuned with a set of
application parameters. The application parameters are organized in
functional groups and have factory-set default values. The default
parameter values are adjusted during commissioning to the specific
application of the drive to activate the specific control, monitoring and
protection functions for the driven process, and to define the signals and
data to be transferred between drive and external equipment.
For further information on the parameters, signal allocation, signal type
selection, signal inversion, scaling and filtering, see
table provided.
