Speed [r/min]
(Note 2) Acceleration/deceleration time constant [ms]
(Note 1) Travel distance [pulse]
Note 1. The unit of move distance can be changed using feed length multiplication factor selection of parameter No.PA05.
2. Acceleration time constant refers to time required to reach the rated speed from stop status (0r/min), and deceleration time
constant refers to time required to reach 0r/min from the rated speed.
The following shows the operation condition settings and the operation procedures.
