Acceleration time
constant
Set the acceleration time taken from 0 r/min (0 mm/s) to the rated speed for the command.
If the servo motor is started with a value exceeding 20000 ms, [AL. F4] will occur, and the servo
motor will not operate.
For example for the servo motor of 3000 r/min rated speed, set 3000 (3 s) to increase speed from 0
r/min to 1000 r/min in 1 s.
Setting range: 0 to 50000
0 [ms]
PT50
STB
Deceleration time
constant
Set the deceleration time taken from the rated speed to 0 r/min (0 mm/s) for the command.
If the servo motor is started with a value exceeding 20000 ms, [AL. F4] will occur, and the servo
motor will not operate.
When the servo motor is started with a value exceeding 20000 ms in the indexer mode, the
deceleration time constant is clamped to 20000 ms.
Setting range: 0 to 50000
