5.13.9 Start signal operation selection / Stop selection
Select the stopping method (deceleration to stop or coasting) 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.
*1 This setting value is valid only in External operation mode.
Stop selection
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.
