13 S-pattern acceleration/deceleration time constant
This is used to smooth start/stop of the servo motor.
Set the time of the arc part for S-pattern
acceleration/deceleration.
STA: Acceleration time constant ([Pr. 11])
STB: Deceleration time constant ([Pr. 12])
STC: S-pattern acceleration/deceleration time constant
([Pr. 13])
If STA (acceleration time constant) or STB (deceleration
time constant) is set to be longer, an error may occur in
the time of the arc part for the S-pattern
acceleration/deceleration time constant setting.
The upper limit value of the actual arc part time is limited
by
2000000
STA
for acceleration or by
2000000
STB
for
deceleration.
(Example) When STA, STB, and STC are set to 20000,
5000, and 200, respectively, the actual arc
part time is as follows.
Because of
2000000
20000
= 100 [ms] <
200 [ms]
,
it is limited to 100 [ms].
At time of
acceleration:
100 [ms]
Because of
2000000
5000
= 400 [ms] >
200 [ms]
,
it becomes 200 [ms] as
designed.
At time of
acceleration:

PC03 S-pattern acceleration/deceleration time constant
This is used to smooth start/stop of the servo motor.
Set the time of the arc part for S-pattern
acceleration/deceleration.
Set the same value as for MR-J2S-_A_.
0 S
T
14 Torque command time constant
This is used to set the constant of a primary delay to the
torque command.
TQC: Torque command time constant
0
PC04 Torque command time constant
This is used to set the constant of a primary delay to
the torque command.
Set the same value as for MR-J2S-_A_.
0 T
15 Station
number
setting
Specifies the station No. of serial communication.
Always set one station to one axis of the servo amplifier.
Setting one station number to two or more stations will
disable a normal communication.
