    The transition between the safe and the unsafe state is initiated via level changes at the control ports STO-A and STO-B of the safety module CAMC-G-S1. According to the safety function specification, the two levels must be identical otherwise an error message will be generated. The finite state machine in the motor controller internally monitors the driver supply voltage after the control ports have been activated.

  • Page 18: Status Display

    In this case, it cannot always be guaranteed that power end stage has been safely switched off. The safety module CAMC-G-S1 controls only the provisioning of the driver supply for the motor con­ troller CMMP-AS-…-M3. Although input voltage levels are monitored area by area, the safety module does not have its own error analysis function and is unable to display errors.
  • Page 19 The finite state machine in motor controller CMMP-AS-...-M3 has its own status in parallel to the safety module CAMC-G-S1. Due to the discrepancy time analysis, this finite state machine may reach the “Safe status” only with a considerable delay. Accordingly, this state can also be signalled via digital outputs or a fieldbus only with a considerable delay.
