*To reset an error condition: Remove input signals; then reapply an input signal to either
CN2-1 (RUN) or CN2-2 (DIR)
**If thermal device recovery is set for automatic, the error will reset 1min after the
temperature has reached operating range, and as long as no external input has been
applied.
Back EMF error
If card detects back EMF over 40V DC for 2sec or 60V DC for 0.1sec the motor will stop running
and go into dynamic brake condition to slow the product down.
Automatic Recovery
-
The roller will automatically restart 1sec after the voltage goes below 30V DC with a run
signal active
Manual Recovery
-
Can only be reset 1sec after the voltage goes below 30V DC
-
To reset an error condition: Remove input signals; then reapply an input signal to either
CN2-1 (RUN) or CN2-2 (DIR)
