14.32 Circular Feed in Manual Mode
Operation
The following shows how to enable the circular feed in manual mode.
(1) Select either JOG mode or handle mode.
(2) Set the coordinates of reference point (h1, v1), gradient arc center (h2, v2), moving range (± h', ± v'), operation mode
(arc), and plane to the specified R register.
(3) Turn ON the "Circular feed in manual mode valid" signal.
When circular feed in manual mode is performed while the axis is moving with JOG feed or handle feed, both H axis and V
axis automatically stop, and then circular feed in manual mode is enabled.
[Operation example]
 When handle feed is performed in the "+" direction of H axis at the current position (point "A"), the axis position moves to
point "B".
Following this operation, when handle feed is performed in the "-" direction of H axis at point "B", the axis position moves to
point "A". The movement is done along the circumference of the arc whose radius is the distance from the arc center to the
current position (point "A").
 When handle feed is performed in the "-" direction of V axis at the current position (point "A"), the axis position moves to
point "C".
Following this operation, when handle feed is performed in the "+" direction of V axis at point "C", the axis position moves to
point "A".
Jog/handle synchronous mode during circular feed in manual mode
Jog/handle synchronous mode can be designated during circular feed in manual mode. Operations during jog/handle
synchronous mode are as follows.
 Oblique linear interpolation
[When handle feed is designated during JOG feed operation]
When the designation is for the handled axis, JOG feed will still be applied.
When the designation is for the other axis, both JOG and handle feeds will be applied for respective axes. G0 time constant
will be applied in the handle feed.
[When JOG feed is designated during handle feed operation]
When the designation is for the handled axis, JOG feed will be applied instead of handle feed.
When the designation is for the other axis, handle feed will still be applied.
When JOG feed is performed on H axis and V axis at the same time when the gradient is 90° or 270°, only JOG feed on H
axis is processed.
When the gradient is 180°, both JOG and handle feeds are processed on respective axes. G0 time constant will be applied on
the handle feed.
 Circular interpolation
[When handle feed is designated during JOG feed operation]
When the designation is for the handled axis, JOG feed will still be applied.
When the designation is for the other axis, both JOG and handle feeds will be applied for respective axes. G0 time constant
will be applied in the handle feed.
[When JOG feed is designated during handle feed operation]
When the designation is for the handled axis, JOG feed will be applied instead of handle feed.
When the designation is for the other axis, handle feed will still be applied. G0 time constant will be applied in the handle feed.
