Fig. 6-132: Stop during external operation
NOTE If Pr. 250 "Stop selection" is set to other than "9999" to select coasting to a stop, the motor
will not be coasted to a stop but decelerated to a stop by the PU stop function during exter-
nal operation.
To restart after the inverter is stopped by PU with PLC function, reset using a power supply
reset or the RES signal (sending stop signal from GX Developer, can also perform the
reset.)
WARNING:
P
Do not reset the inverter with the start signal on. Doing so will cause the inverter to
start immediately after a reset, leading to hazardous conditions.
