Figure 3-14 AMC circuit board example
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
For more information on control, protection and monitoring functions, see the
“Appendix G - Signal and parameter table”.
3.2.5.4. Main circuit breaker
The main circuit breaker (MCB) is an important switching and protection device of
the drive system. Therefore it must only be controlled and monitored by the drive.
For more information, see:
– “Main circuit breaker specification” (3BHS125149 E60)
– “2.7 Important note - main circuit breaker” on page 37.
