Determined by the command pulse frequency from the controller.
Set according to the manual of the controller to be used.
S
This mode can be set with [Pr. PC01 Speed acceleration time constant] and [Pr. PC02 Speed
deceleration time constant]. By turning on the STAB2 (Speed acceleration/deceleration
selection), the speed control mode will be changed to the value set in [Pr. PC30 Speed
acceleration time constant 2] and [Pr. PC31 Speed deceleration time constant 2].
