[Pr.423] Auxiliary shaft clutch reference address setting
Select the address type to be used as the reference address for clutch control. Note that
the processing order of the auxiliary shaft gear and the auxiliary shaft clutch will change
depending on the reference address setting.
0: Auxiliary shaft current value .... The clutch is controlled by using the current value for
the servo input axis/synchronous encoder axis that is
set for the auxiliary shaft.
Output after the clutch is a converted travel value
through the auxiliary shaft gear.
1: Current value per cycle after auxiliary shaft gear
.............. The clutch is controlled by using the current value per
cycle after auxiliary shaft gear.
Output after the clutch is a travel value without
conversion.
The setting values for the following parameters are in units based on the reference
address setting.
• "[Pr.424] Auxiliary shaft clutch ON address"
• "[Pr.426] Auxiliary shaft clutch OFF address"
• "[Pr.425] Travel value before auxiliary shaft clutch ON", "[Pr.427] Travel value before
auxiliary shaft clutch OFF"
• "[Pr.430] Slippage amount at auxiliary shaft clutch ON", "[Pr.431] Slippage amount at
auxiliary shaft clutch OFF"
[Pr.424] Auxiliary shaft clutch ON address
Set the clutch ON address when address mode is configured for the ON control mode of
the auxiliary shaft clutch.
When the reference address is the current value per cycle after auxiliary shaft gear, the
setting address is converted for control within the range from 0 to (Cam axis length per
cycle - 1).
Example) Cam axis length per cycle: 20000PLS
The ON address is controlled as 19000PLS when the setting value is "-1000".
