14.32 Circular Feed in Manual Mode

14.32.3 Precautions

(1) This function is available in the JOG or handle mode, manual rapid traverse and incremental feed.
(2) This function works for the H axis and V axis. This function cannot be used for the other NC axes and PLC axis. When
this function is valid, all the axes other than H axis and V axis move as usual.
(3) When the manual interlock is applied to either H or V axis, the movement of both axes stops.
(4) The following cases do not allow the circular feed in manual mode. In these cases, all axes cannot be moved until the
"Circular feed in manual mode valid" signal is turned OFF.
(a) Either H axis or V axis is in machine lock. (In this case, even machine lock is not performed.)
(b) The reference position return of either H axis or V axis is not completed.
(c) Either H axis or V axis is in servo OFF.
(d) Either H axis or V axis is detached.
(e) The CNC is in one of the following states.
- In automatic operation (OP)
- Emergency stop
- Reset
(f) The current position is outside of the specified travel range.
(g) The setting value which is specified with R register is illegal.
(5) Executing the automatic operation turns this function invalid. In this case, all axes cannot be moved until the "Circular
feed in manual mode valid" signal is turned OFF.
(6) When this function is used, the feedrates is clamped so that the resultant speed of H axis and V axis does not exceed the
slower traverse rate of the two axes.
(7) When this function is ON and the either axis is moving beyond the travel range, both axes stop.
(8) When this function is ON, if a change of the travel range makes the current position out of the range, both H and V axes
cannot be moved until the range is amended to include the current position.
(9) When the status of the "Circular feed in manual mode valid" signal is changed, the axis being moved in the manual mode
temporarily stops for safety.
(10) When the movement on V axis is made with the current position and the arc center overlapped in the linear-arc mode, the
movement is done along the minimum travel area of the H axis.
(11) Circular feed in manual mode is disabled when the gradient between H axis and V axis is 0 degree in the linear-linear
mode. In this case, both H axis and V axis cannot be moved until the "Circular feed in manual mode valid" signal (YC7E)
is turned OFF.
