4 ADVANCED SYNCHRONOUS CONTROL
4.7 Synchronous Control Monitor Data
Change method 1): The new position value after composite main shaft gear is calculated based on the current value of the
main input axis.
Position value after composite main shaft gear = Main input direction of composite main shaft gear Main input axis current
value
Change method 2): The movement amount of the main input axis from the last synchronous control session is reflected to the
position value after composite main shaft gear.
Position value after composite main shaft gear = Position value after composite main shaft gear Movement amount of main
input axis from the last synchronous control session
[Md.401] Position value per cycle after main shaft gear
The input movement amount after the main shaft gear is stored within the range from 0 to (Cam axis length per cycle - 1). The
unit is in cam axis cycle units (Page 123 Units for the output axis).
The value is restored according to "[Pr.460] Setting method of position value per cycle after main shaft gear" when starting
synchronous control. (Page 139 Synchronous Control Initial Position)
[Md.402] Position value per cycle after auxiliary shaft gear
The input movement amount after the auxiliary shaft gear is stored within the range from 0 to (Cam axis length per cycle - 1).
The unit is in cam axis cycle units (Page 123 Units for the output axis).
The value is restored according to "[Pr.461] Setting method of position value per cycle after auxiliary shaft gear" when starting
synchronous control. (Page 139 Synchronous Control Initial Position)
[Md.406] Cam axis phase compensation amount
The phase compensation amount for the cam axis is stored with cam axis cycle units (Page 123 Units for the output axis).
The phase compensation amount after smoothing processing with " [Pr.445] Cam axis phase compensation time constant" is
stored.
[Md.407] Cam axis position value per cycle
The cam axis position value per cycle is stored within the range from 0 to (Cam axis length per cycle - 1).
The current value after cam axis phase compensation processing can be monitored. The unit is in cam axis cycle units
(Page 123 Units for the output axis).
The value is restored according to "[Pr.462] Cam axis position restoration object" when starting synchronous control.
(Page 139 Synchronous Control Initial Position)
[Md.408] Cam reference position
The command position value is stored as the cam reference position. The unit is in output axis position units (Page 123
Units for the output axis). When the unit is in degrees, a range from 0 to 35999999 is used.
The value is restored according to "[Pr.462] Cam axis position restoration object" when starting synchronous control.
(Page 139 Synchronous Control Initial Position)
[Md.409] Cam axis command position value
The command position value of the cam axis is stored. The value is the same as "[Md.20] Command position value" during
synchronous control.
[Md.410] Execute cam No.
The executing cam No. is stored.
When "[Pr.440] Cam No." is changed during synchronous control, this is updated when the controlling cam No. switches.
[Md.411] Execute cam stroke amount
The executing cam stroke amount is stored.
When "[Pr.441] Cam stroke amount" is changed during synchronous control, this is updated when the controlling cam stroke
amount switches.
