8376
Chopping compensation scaling factor
[Data type] Byte
[Unit of data] %
[Valid data range] 0 to 100
This parameter specifies a scaling factor used to multiply the
compensation value for a servo delay or acceleration/deceleration
delay in an chopping operation. When this parameter is set to 0, servo
delay compensation will not be applied.
8377
Compensation start tolerance
[Data type] Word
[Unit of data]
Input increment IS-A IS-B IS-C Unit
Metric machine 0.01 0.001 0.0001 mm
Inch machine 0.001 0.0001 0.00001 inch
Rotary axis 0.01 0.001 0.0001 deg
[Valid data range] 0 to 32767
Compensation is applied when the difference between an amount of
shortage at the upper dead point and that at the lower dead point is less
than the value specified in this parameter. In other words, this
parameter is used to enable compensation after the chopping operation
settles. When the parameter is set to 0, compensation will not be
applied.
8378
Amount of an error permissible for starting increase in speed
[Data type] 2-word
[Unit of data]
Input increment IS-A IS-B IS-C Unit
Metric input 0.01 0.001 0.0001 mm
Inch input 0.001 0.0001 0.00001 inch
Rotary axis 0.001 0.0001 0.00001 deg
[Valid data range] 0 to 99999999
This parameter sets the amount of an error permissible for starting
increase in speed.
When the amount of shortage at the lower dead point becomes smaller
than the value set in this parameter, clamping at the maximum
chopping feedrate is not performed.
