Description
Disable voltage
(High priority stop) 7, 9, 10, 12 xxxx xx0x Stop operation (current loop off) from any STATE and after FAST STOP ACTIVE.
Shutdown
(Stop command) 2, 5, 6, 8 xxxx x110 Command to get to READY TO SWITCH ON after SWITCH ON DISABLED or fault
reset. Command to stop the drive if it is running.
Switch on * 3 xxxx x111 Command to get (from READY TO SWITCH ON) to SWITCHED ON state can be
replaced by Enable operation for running
Fast stop 7, 10, 11 xxxx x01x Stop as fast as possible (with current )
Power-up successfull * 1 Needs no command as it is done inside the module itself
Enable operation 4 xxxx 1111 Start the drive if previous states are SWITCHED ON or READY TO SWITCH ON.
Reset fault 15 0xxx xxxx to
1xxx xxxx Comand to clear a present fault
* These transitions are not needed for operation.
Note: The state SWITCHED ON is like power on to the drive, but this is a virtual state because the power to
the drive is applied all the time in our case.
