Plane Composition; Normal Line Control - Mitsubishi Electric MELSEC iQ-R16MTCPU Programming Manual

Plane composition

Base axis I/Base axis J/Base axis K
Set the axis names of the base axes for which the plane is composed.
Set the axis names set here to [Motion Control Parameter][G-code Control Parameter][G-code Control Axis
Parameter]"Line Axis Information""Axis name" also.
When using two axes etc., set "0" to items that are not used (Base axis I, Base axis J, Base axis K).
Normally, by setting X, Y, and Z to "Base axis I", "Base axis J", and "Base axis K", the following relationships are established.
When setting axis names other than the following, set any given axis name.
• G17: X-Y
• G18: Z-X
• G19: Y-Z
When the axis names set to "Base axis I", "Base axis J", and "Base axis K" are the same, or the set axis names have not been
set in [Motion Control Parameter][G-code Control Parameter][G-code Control Axis Parameter]"Line Axis
Information""Axis name", a moderate error (error code: 30FDH (details code: 0010H)) occurs.

Normal line control

Normal line control axis
Set the axis names of the axes performing normal line control.
When the axes of the specified names have not been set, a moderate error (error code: 30FDH (details code: 0011H)) occurs.
Set the axis name of a rotating axis for normal line control axes. When an axis name of a linear axis is set, a moderate error
(error code: 30FDH (details code: 0012H)) occurs.
The axis names of axes set to "Base axis I", "Base axis J", "Base axis K" cannot be set to normal line control axes. When set
to normal line control axes, a moderate error (error code: 30FDH (details code: 0012H)) occurs.
Normal line control type
Set the normal line control type.

1: Normal line control ■At start
type 
Direction for which there is less than
180[degree] (shortest way)
■Other than start
Command direction
Minimum rotating angle
Set the minimum rotating angle of a normal line control axis at a block joint during normal line control.
Normal line control axis rotating speed
Set the normal line control axis rotating speed of the block joint during normal line control.
Normal line control axis rotating speed is enabled for normal line control type .
When the value set in normal line control axis rotating speed exceeds the normal line control axis value set in [G-code Control
Axis Parameter]"Speed/Time Constant""Cutting Feed Clamp Speed", a moderate error (error code: 30FDH(details code:
012H)) occurs.
Rotating speed for block joint
Parameter speed setting
The speed at which the blade of the tool follows the command speed.
Rotating speed for circular interpolation
The speed at which the program path follows the
command speed.
