Alarm Input Function
All motion is aborted when the alarm input is triggered – regardless of the direction of the
motor. Once the alarm error is set, the status must be cleared (using the
CLR command)
in order to move again. The alarm switch function can be disabled using the DL
command. By disabling the alarm switch function, the limits switches can be used as a
general purpose input
Note: The DL command controls both the limit switch function as well as the alarm input
function.
Alarm input is active high.
Configuration Button Function
Configuration button is used to configure the DMX-K-DRV, DMX-A2-DRV, and ACE-
SDX. Configuration button can also be used as general purpose digital input in the
standalone program.
The configuration button is active high.
