Acknowledging a Reset After an Error (output bit 5)
The host should use the Reset output bit to acknowledge an error after the cause
of the error has been corrected.

Reset: Acknowledge error
1 = reset
If the error condition has shut down the motor, the cause of the error must be
removed to restart the motor. After correcting the error condition, the control
system should set the Reset Acknowledge output bit. The error can also be
acknowledged in manual mode by inserting the Motor Starter Pendent, which
places the module into manual mode.
If the underlying cause of the error is not removed, the error message will continue
to be reported in the input data.
CAUTION
Following a critical error, do NOT issue repeated Reset commands before
correcting the fault. Resetting the module before fully correcting the error can
cause damage to the equipment or personal injury.
If the Motor Starter Module accepts the Reset Acknowledgement, the error codes
are removed from the input data. The Reset bit must remain set until the error
code is reset.
Timing for Reset Acknowledgement
▪
If an Overcurrent error (error code 11) occurs, an acknowledgement will not be
accepted until recovery time of at least 60 seconds has passed.
▪
A Power Level error (error code 10) can be acknowledged after 0.3 second.
The module's built-in timer is not immediately reset after receiving a Reset
Acknowledgement command. Depending on the reason for the shutdown, the
counter is not reset until approximately 2 to 3 minutes after the motor is switched
off.
