Misoperation prevention and parameter setting restriction
PU stop selection
In any of the PU operation, external operation and network operation modes, the motor can be
stopped by pressing the STOP key of the PU.
When the inverter is stopped by the PU stop function (refer to section 4.3 "Operation panel") in
the external operation mode, "PS" is displayed but an alarm is not output. An alarm output is not
provided.
After the motor is stopped from the PU, it is necessary to perform PU stop (PS) reset to restart.
PS reset can be made from the unit from which PU stop is made (operation panel, parameter unit
(FR-PU04/PU07, operation panel for FR-E500 (PA02)).
The motor can be restarted by making PS cancel using a power supply reset or RES signal.
When Pr. 75 is set to any of "0 to 3", PU stop (PS display) is invalid, deceleration to a stop by the
STOP key is valid only in the PU operation mode.
NOTE During operation in the PU operation mode through RS485 communication from the PU con-
nector, the motor decelerates to stop (PU stop) when STOP is entered from the operation
panel.
