An internal fault during self-checking will cause an alarm. Since operation
may be erratic depending on the fault condition, it may be desirable to trip
the motor by setting this setpoint to ENABLE. The MM3 continues to run
the motor with an internal fault present if set to DISABLE.
Range: 5 to 25 seconds or OFF; Step: 5 seconds
If the serial communications link is used to control a process with several
motors working together, it may be desirable to shut down the motor if
communication control is lost. When no activity occurs on the
communications port for 5 to 25 seconds, it will trip if this feature is
enabled.
Range: 5 to 25 seconds or OFF; Step: 5 seconds
Sets an alarm when the serial communication link is interrupted.
Range: ENABLE, DISABLE
Allows the command mode to automatically switch from AUTO to
MANUAL when the SERIAL COMMS FAILURE ALARM is active. If the motor
was running when the alarm occurred it will be stopped and will restart
based on manual start inputs only. When serial communication is
restored the MM3 will remain in MANUAL command mode.
