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
Note:
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.
Note:
For more information, see:
• "Main circuit breaker specification" (3BHS125149 E60)
• “2.7 Important note - main circuit breaker” on page 47.
