during
decelera-
tion Used to select a function to change the decel-
eration time of the motor automatically so that
there will be no overvoltage imposed on the
motor during deceleration.
0: Stall prevention during deceleration enabled
1: Stall prevention during deceleration disabled
* Be sure to set the parameter to 1 when the
Braking Resistor Unit or a braking resistor is
used as an option.
