5.16.10 Stop selection
Select the stopping method (deceleration stop or coasting) at turn-OFF of the start signal.
Coasting can be selected for the cases such that the motor is stopped with a mechanical brake at turn-OFF of the start signal.
The operation of the start signal (STF/STR) can be selected. (For the start signal selection, refer to page 502.)
*1 For the start signal selection, refer to page 502.
To decelerate the motor to a stop
•Set Pr.250 = "9999 (initial value) or 8888".
• The motor is decelerated to a stop when the start signal (STF/STR) is turned OFF.
To coast the motor to a stop
• Set the time required to shut off the output after the start signal is turned OFF in Pr.250. When "1000 to 1100" is set, output
is shut off after a lapse of the (Pr.250 - 1000) seconds.
• The output is shut off after a lapse of the setting time of Pr.250 when the start signal is turned OFF. Motor coasts to a stop.
• The RUN signal is turned OFF when the output is shut off.
