STA: Acceleration time constant ([Pr. PC01])
STB: Deceleration time constant ([Pr. PC02])
STC: S-pattern acceleration/deceleration time constant ([Pr. PC03])
Long setting of STA (acceleration time constant) or STB (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 upper limit value of the actual arc part time is limited by
2000000
STA
for acceleration or by
2000000
STB
for deceleration.
(Example) At the setting of STA 20000, STB 5000 and STC 200, the actual arc part
times are as follows.
Acceleration: 100 ms
2000000
20000
= 100 [ms] < 200 [ms]
Therefore, it will be limited to 100 ms.
Deceleration: 200 ms
2000000
5000
= 400 [ms] > 200 [ms]
Therefore, it will be 200 ms as you set.
