acceleration/
deceleration
time constant This parameter is used to smooth the start/stop of the servo motor or linear servo
motor.
Set the time of the arc part for S-pattern acceleration/deceleration.
Setting "0" will make it linear acceleration/deceleration.

A long time constant set in STA ([Pr. PT49 Acceleration time constant]) or STB ([Pr.
PT50 Deceleration time constant]) may produce an error in the time of the arc part
for the setting of the S-pattern acceleration/deceleration time constant. The setting
will be disabled at home position return.
In the profile mode
When a value of 1000 ms or larger is set, the parameter value will be clamped to
1000 ms. The setting will be disabled at home position return.
Specify STA ([Pr. PT49 Acceleration time constant]) and STB ([Pr. PT50
Deceleration time constant]) with "Profile acceleration (Class ID: 64h, Ins ID:
6083h, Attr ID: 0)" and "Profile deceleration (Class ID: 64h, Ins ID: 6084h, Attr ID:
0)".
This function will be enabled in the profile position mode and profile velocity mode.
To enable this function, cycle the power after 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 = 20000, STB = 5000 and STC = 200, the actual arc part
times are as follows.
At acceleration: 100 ms
2000000
20000
= 100 [ms] < 200 [ms]
Therefore, it will be limited to 100 [ms].
At deceleration: 200 ms
2000000
5000
= 400 [ms] > 200 [ms]
Therefore, it will be 200 [ms] as you set.
