3 BASIC FUNCTION
3.20 Acceleration/deceleration function [G] [A]
Setting method [G]
The setting method varies for each control mode. Refer to the following table. In addition, the deceleration time constant of the
forced stop deceleration function can be set with [Pr. PC24 Deceleration time constant at forced stop].
Page 171 Forced stop deceleration function
*1 Available on servo amplifiers with firmware version A5 or later.
*2 Available on servo amplifiers with firmware version B8 or later.
Setting method [A]
The setting method varies for each control mode. Refer to the following table. In addition, the deceleration time constant of the
forced stop deceleration function can be set with [Pr. PC51 Deceleration time constant at forced stop].

Control mode Symbol Setting method
Position control mode P Determined by the command pulse frequency from the controller.
Set according to the manual of the controller to be used.
Speed control mode 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].

Torque control mode T 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].
