at the same time, the Drive will decelerate to stop.
Motor Coast-To-Stop
Input Terminal/Reset
Input
Motor will coast-to-stop with BX-CM (closed) (For use when
applying mechanical brake with Drive operation.) Note. If
BX-CM is opened with FWD or REV closed, the Drive will start
operating
External thermal trip
c o m m a n d
CONTROL TERMINAL BOARD
After removal of fault Faults are reset when a momentary
contact closure is made between the RST-CM terminals for more
than 0.1 seconds.
NOTE: If there an to the FWD and/or REV terminals, the unit
not RESET.
With THR-CM (open), OH trip occur and the motor will
coast-to-stop.
NOTE: With no external thermal relay or external braking resistor
thermostat, THR-CM must be closed or the
not operate.
