3 BASIC FUNCTION
3.18 Acceleration/deceleration function
Setting method [G] [WG]
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].

*1 Available on servo amplifiers with firmware version A5 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].

pp
Can be set with [Profile acceleration (Obj. 6080h)] and [Profile deceleration (Obj. 6084h)].
Can also be set with [Pr. PT49 Speed acceleration time constant] and [Pr. PT50 Speed
deceleration time constant].
Profile velocity mode
pv
Can be set with [Profile acceleration (Obj. 6080h)] and [Profile deceleration (Obj. 6084h)].
Can also be set with [Pr. PT49 Speed acceleration time constant] and [Pr. PT50 Speed
deceleration time constant].
Profile torque mode
tq
The amount of torque change can be set with [Torque slope (Obj. 6087h)].
Homing mode
hm
This mode can be set with [Homing acceleration (Obj. 609Ah)].

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].
