NOTE
If 0 is specified, the value of parameter No. 1425 is used.
8021 Minimum speed of rapid traverse override in axis control by PMC (Fo)
[Data type] Word axis
[Unit of data, Valid data range]
Valid data range
Increment system Unit of data
IS–B IS–C
Millimeter machine 1 mm/min 6 to 15000 6 to 12000
Inch machine 0.1 inch/min 6 to 6000 6 to 4800
Rotation axis 1 deg/min 6 to 15000 6 to 12000
This parameter specifies the minimum speed of rapid traverse override on
a PMC–controlled axis (Fo).
8022 Upper–limit rate of feed per revolution during PMC axis control
[Data type] Word
[Unit of data]
[Valid data range]
Valid data range
Increment system Unit data
IS–B IS–C
Millimeter machine 1 mm/min 6 to 15000 6 to 12000
Inch machine 0.1 inch/min 6 to 6000 6 to 4800
Rotation axis 1 deg/min 6 to 15000 6 to 12000
This parameter sets the upper limit rate of feed per revolution during PMC
axis control.
NOTE
The upper limit specified for the first axis is valid for all axes.
The specifications for the second and subsequent axes are
ignored.
8028 Linear acceleration/deceleration time constant for speed commands for PMC axis control
[Data type] Word axis
[Unit of data] ms/1000 min
-1
[Valid data range] 0 to 32767
This parameter sets the time required for the servo motor rotation speed
to increase or decrease by 1000 min
–1
, for each axis, as a linear
acceleration/deceleration time constant for speed commands for PMC
axis control.
NOTE
If this parameter is set to 0, acceleration/deceleration control
is not applied.
