Example
The following shows an example of starting a cam pattern from the zero point of the cam
axis current value per cycle with the current feed current value position as the origin when
returning to a specified point, or home position return is completed after a forced stop.
Setting item
[Pr.439] Cam axis length per cycle
[Pr.441] Cam stroke amount
[Pr.462] Cam axis position restoration object
[Pr.463] Setting method of cam reference position
[Pr.464] Setting method of cam axis current value per cycle
[Pr.467] Cam reference position (Initial setting)
[Pr.468] Cam axis current value per cycle (Initial setting)
• Move to synchronous control starting point
Feed current value [PLS]
150
0
Move to the position of 150 [PLS] by
return to cam starting position, or by home position return.
• Restore operation at start of synchronous control
Feed current value [PLS]
150

Cam axis current
value per cycle [PLS]
0
Chapter 5 Synchronous Control Initial Position
Time [ms]
Start synchronous control.
The cam reference position (feed current value = 150 [PLS])
becomes the equivalent for the position where
"Cam axis current value per cycle = 0 [PLS]".
Time [ms]
Operation starts from the position "Initial setting = 0 [PLS]"
of the setting method of cam axis current value per cycle.
Time [ms]
5 - 20
