14.2 Manual Speed Command
Restrictions and precautions regarding manual speed command 2
(1) When using this function involving multiple part systems, the manual mode (handle/JOG/rapid traverse), the manual
speed command reverse run valid signal and the manual speed command sign reversed signal must be the same
between part systems where the manual speed command is enabled.
(2) When using rapid traverse (G0) in this function, set "#1086 G0Intp" to "0".
If "#1086 G0Intp" is set to "1" (Non-interpolation), the handle speed/JOG/manual rapid traverse rate of the smallest part
system No. among the part systems where the manual speed command is enabled is applied to the G0 speed. However,
relations of travel paths and travel speeds between part systems may be different from those of an actual automatic oper-
ation.
(3) The handle speed/JOG/manual rapid traverse rate of the smallest part system No. between part systems where the man-
ual speed command is enabled is applied to a movement from the intermediate point to the reference position of G28/
G30 (reference position return) and a movement from the start point to the intermediate point of G29. These movements
are non-interpolation type; therefore, machining conditions (related to travel paths and travel speeds) between part sys-
tems may be different from those of an actual automatic operation.
(4) For constant surface speed control, the S command before commanding the constant surface speed control is used.
When constant surface speed control is used, the relation of feedrates between part systems may be different from the
ratio of the actual travel speeds of the tools.
(5) For an inverse time feed, the relation of feedrates between part systems may be different from the ratio of the actual
travel speeds of the tools.
(6) If a reverse run operation is carried out at a single block stop in any of the part systems, the block which is in the single
block stop moves to the next block. The other part systems carry out the reverse run only during the movement.
(7) If any of part systems is in a timing synchronization (a timing synchronization by a ! code or M code, or a timing synchro-
nization with the start point designated (G115/G116)), the rest of the part systems cannot carry out a reverse run.
(8) This function uses the handle speed/JOG/manual rapid traverse rate of the smallest No.'s part system in which the man-
ual speed command is enabled. In the case of using this function in multiple part systems, if the "manual speed command
valid" signal is switched (ON - OFF) while the handle or JOG feed is still carried out, the part system which uses the han-
dle/JOG/manual rapid traverse speed may change and the moving axis's feedrate may also change. Switch the manual
seed command valid signal after stopping the handle/JOG feed.
