Parameter
#7 #6 #5 #4 #3 #2 #1 #0
15840 TRB
[Data type] Bit
TRB Specify whether Gap control B function are enabled or disabled.
0: Disabled
1: Enabled
15850 Machine movement at 1 rotation of motor
[Data type] 2-word axis
[Unit of data] 0.001mm
[Valid data range] 0 to 99999999
Specify the machine movement at 1 rotation of motor for gap control axis.
This parameter should be set in case of using the rotation motor for gap control axis.
The parameters need not to be set except for gap control axis because this parameter is used
only by the gap control function.
15851 Magnification of the position detection circuit
[Data type] 2-word axis
[Unit of data] times
[Valid data range] 0 to 99999999
Specify the magnification of the position detection circuit installed in the separate detector of
gap control axis.
This parameter should be set in case of using the linear motor for gap control axis.
The parameters need not to be set except for gap control axis because this parameter is used
only by the gap control function.
15852 Wavelength of the separate detector
[Data type] 2-word axis
[Unit of data] 0.000001mm
[Valid data range] 0 to 99999999
Specify the wavelength of the separate detector of gap control axis.
This parameter should be set in case of using the linear motor for gap control axis.
The parameters need not to be set except for gap control axis because this parameter is used
only by the gap control function.
15853 Gap control gain
[Data type] Word axis
[Unit of data] sec
-1
[Valid data range] 0 to 32767
Specify the gap control gain to determine the trace performance of the gap control axis.
The gap control speed is determined by multiplying the deflection from the detector by the
gap control gain.
