5.16.9 Stop selection
NOTE
• Stop selection is disabled when following functions are operating.
- Position control (Pr.419 = "0")
- Power failure stop function (Pr.261)
- PU stop (Pr.75)
- Deceleration stop due to fault initiation (Pr.875)
- Deceleration stop due to communication error (Pr.502)
- Offline auto tuning (with motor rotation)
• When Pr.250 "9999 or 8888", acceleration/deceleration is performed in accordance to the frequency command until the
output is shutoff by turning OFF the start signal.
• When the restart signal is turned ON during the motor coasting, the operation is resumed from Pr.13 Starting frequency.
• Even with the setting of coasting to stop, when the LX signal is turned ON, the motor does not coast but zero speed control or
servo lock is applied.

Select the stopping method (deceleration to stop or casting) at turn-OFF of the start signal.
Use this function to stop a motor with a mechanical brake at turn-OFF of the start signal.
Selection of start signal (STF/STR) operation can also be selected. (For start signal selection, refer to page 436.)

STF signal: Start signal
STR signal: Forward/reverse rotation signal
It will coast to stop after
(Pr.250 - 1000) s when the
start signal is turned OFF.
9999
STF signal: Forward rotation start
STR signal: Reverse rotation start
It will perform deceleration
stop when the start signal is
turned OFF.
8888
STF signal: Start signal
STR signal: Forward/reverse rotation signal
Make the motor perform deceleration
stop
•Set Pr.250 = "9999 (initial value) or 8888".
• It will perform deceleration stop when the start signal (STF/STR)
is turned OFF.
Make the motor perform coast to stop
• Set the time from the time the start signal is turned OFF to when
the output is shutoff in Pr.250. When set to "1000 to 1100", output
is shutoff after (Pr.250 - 1000) s.
• The output is shutoff after the set time of Pr.250 has elapsed after
the start signal is turned OFF. The motor will coast to stop.
• The RUN signal will be turned OFF at the time of output stop.
