Control Units For 1 Axis Positioning Control; Control Units For Interpolation Control - Mitsubishi Electric MELSEC Q Series Programming Manual

6 POSITIONING CONTROL

6.1.3 Control units for 1 axis positioning control

6.1.4 Control units for interpolation control

There are axes whose control
unit set in the fixed parameter is
[mm] and [inch].
Normal start
Unit mismatch
Control units of the fixed parameter for all axes differ from the
(Minor error (error
interpolation control units specified with parameter block.
code: 40))
(3) Circular interpolation control
The angular speed is controlled with the setting speed at the circular interpolation
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.)
(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 each axis fixed parameter for the interpolation control, it shown
below.

Starting method
Positioning control starts by the interpolation
control units of 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: pulse > degree > inch > mm
<Example>
If axis is set to 1000[pulse] and 10.000[inch],
10.000[inch] setting is considered to be
10000[pulse].
