The rollers are used in the following cases.
• The machine connected to the servomotor is operated continuously.

controlled without the current value and position data.)
This section describes the roller operation and parameters required to use a roller.

[PLS/s])
(Gear ratio) (Speed change ratio) [PLS/s]
Number of roller
revolution
=
(Drive module travel
