8.1 Rollers

8.1.1 Operation

The rollers are used in the following cases.
• The machine connected to the servomotor is operated continuously.
• The system which does not need position control.
(It is used when the speed control (cycle speed/number of rotations) mainly is
controlled without the current value and position data.)
This section describes the roller operation and parameters required to use a roller.
(1) Operation
(a) The roller is controlled with the speed that the speed/travel value of drive
module multiplied by a gear ratio/speed change ratio of transmission
module, and it rotates for the travel value.
(Drive module speed
Roller speed =
[PLS/s])
Number of roller (Drive module travel
=
revolution value [PLS])
The speed/travel value of drive module transmitted to the roller is
commanded to the servo amplifier.
(b) When a clutch is used, the roller is controlled at clutch ON.
