[Md.408] Cam reference position
The feed current value is stored as the cam reference position. The unit is in output axis position units (Page 118 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 133 Synchronous Control Initial Position)
[Md.409] Cam axis feed current value
The feed current value of the cam axis is stored. The value is the same as "[Md.20] Feed current 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.
[Md.420] Main shaft clutch ON/OFF status
The clutch ON/OFF status is stored.
[Md.421] Main shaft clutch smoothing status
The smoothing status of the clutch is stored. The status is updated by the clutch smoothing method as follows.
Method
Time constant method
Slippage method
[Md.422] Main shaft clutch slippage (accumulative)
The accumulative slippage amount with the slippage method is stored as a signed value.
The absolute value of the accumulative slippage increases to reach the slippage at clutch ON during clutch ON.
The absolute value of the accumulative slippage decreases to reach 0 during clutch OFF.
Monitoring of the accumulative slippage is used to check the smoothing progress with the slippage method.
[Md.423] Auxiliary shaft clutch ON/OFF status
The clutch ON/OFF status is stored.
[Md.424] Auxiliary shaft clutch smoothing status
The smoothing status of the clutch is stored. The status is updated by the clutch smoothing method as follows.
Method
Time constant method
Slippage method
Details
The status is always "1: On clutch smoothing" during the clutch ON status. The status will be "0: Not on clutch
smoothing" when the clutch is turned OFF and smoothing is completed.
The status is "1: On clutch smoothing" till the clutch accumulative slippage amount reaches the slippage at clutch ON
when the clutch is turned ON. The status will change to "0: Not on clutch smoothing" when the clutch accumulative
slippage amount reaches the slippage at clutch ON. The status is "1: On clutch smoothing" till the clutch accumulative
slippage amount reaches 0 when the clutch is turned OFF. The status will change to "0: Not on clutch smoothing" when
the clutch accumulative slippage amount reaches 0.
Details
The status is always "1: On clutch smoothing" during the clutch ON status. The status will be "0: Not on clutch
smoothing" when the clutch is turned OFF and smoothing is completed.
The status is "1: On clutch smoothing" till the clutch accumulative slippage amount reaches the slippage at clutch ON
when the clutch is turned ON. The status will change to "0: Not on clutch smoothing" when the clutch accumulative
slippage amount reaches the slippage at clutch ON. The status is "1: On clutch smoothing" till the clutch accumulative
slippage amount reaches 0 when the clutch is turned OFF. The status will change to "0: Not on clutch smoothing" when
the clutch accumulative slippage amount reaches 0.
