6 POSITIONING CONTROL
(3) Circular interpolation control
The angular speed is controlled with the setting speed at the circular interpolation
control.
Control with the setting speed
6.1.3 Control units for 1 axis positioning control
It is controlled in the control units specified with the fixed parameters at the 1 axis
positioning control.
(The control unit specified with the parameter block is ignored.)
6.1.4 Control units for interpolation control
(1) The interpolation control units specified with the parameter block and the control
units of the fixed parameter are checked.
If the interpolation control units specified with the parameter block differ from the
control units of the each axis fixed parameter for the interpolation control, it shown
below.
Interpolation control units in the parameter block
mm inch degree PLS
Starting method
Condition for
normal start
There are axes whose control
unit set in the fixed parameter is
[mm] and [inch].
There are axes
whose control
unit set in the
fixed parameter
is [degree].
There are axes
whose control
unit set in the
fixed parameter
is [PLS].
Positioning control starts by the interpolation
control units of parameter block.
Condition for
unit mismatch error
(Error code [40])
Control units of the fixed parameter for all axes differ from the
interpolation control units specified with parameter block.
• If the control units of axes to be interpolation-
controlled are the same, control starts in the
preset control unit.
• If the control units of axes to be interpolation-
controlled are different, control starts in the unit
of highest priority as indicated below.
Priority: PLS > degree > inch > mm
<Example>
If axis is set to 1000[PLS] and 10.000[inch],
10.000[inch] setting is considered to be
10000[PLS].
