B-63943EN-1/02 17.PMC CONTROL FUNCTION
- 2013 -
8030
Time constant for exponential acceleration/deceleration in cutting feed or
continuous feed under PMC axis control
[Input type] Parameter input
[Data type] 2-word axis
[Unit of data] msec
[Valid data range] 0 to 4000
For each axis, this parameter sets a time constant for exponential
acceleration/deceleration in cutting feed or continuous feed under
PMC axis control.
NOTE
When 0 is set in this parameter, the value set in
parameter No. 1622 is used.
The value set in parameter No. 1622 is used also
for linear acceleration/deceleration after cutting
interpolation.
8031
FL feedrate for exponential acceleration/deceleration in cutting feed or
continuous feed under PMC axis control
[Input type] Parameter input
[Data type] Real axis
[Unit of data] mm/min, inch/min, degree/min (machine unit)
[Minimum unit of data] Depend on the increment system of the applied axis
[Valid data range] Refer to the standard parameter setting table (C)
(When the increment system is IS-B, 0.0 to +240000.0)
For each axis, this parameters sets a lower feedrate limit (FL feedrate)
for exponential acceleration/deceleration in cutting feed or continuous
feed under PMC axis control.
NOTE
When 0 is set in this parameter, the value set in
parameter No. 1623 is used.
However, be sure to set 0 in this parameter and
parameter No. 1623 for all axes at all times except
for special purposes. If a value other than 0 is
specified, correct linear or circular figures cannot
be obtained.
