14.2 Manual Speed Command
Contact Signal name
A MANUAL SPEED COMMAND VALID
[Function]
This signal is used to run the machining program with handle feedrate or JOG feedrate (manual feedrate).
[Operation]
After this signal is ON, manual speed (handle or manual feedrate) is applied to the axis feedrate in the whole automatic
operation: the speed commanded in the program is not used.
If the program has not started, the automatic operation start is executed with handle or manual feedrate.
The manual operation mode decides whether the manual feedrate or handle feedrate is used.
<In handle mode>
The program under operation is executed at the feedrate of the 1st handle, 1st axis.
During the reset, block stop or pause in the automatic operation mode, the automatic operation starts at the time when the
handle feedrate has been commanded.
When the reverse run is valid, a command in the (+) direction makes the movement as in the program, while a command
in (-) direction reverses the movement against the program. The reversed movement, however, is available only within the
current block.
<In JOG mode>
The program under operation is executed at the manual feedrate as long as the JOG mode signal is ON for the 1st axis.
During the reset, block stop or pause in the automatic operation mode, the automatic operation starts at the time when the
JOG mode has been turned ON.
When the reverse run is valid, a command in the (+) direction makes the movement as in the program, while a command
in (-) direction reverses the movement against the program. The reversed movement, however, is available only within the
current block.
When the "Rapid traverse" signal is ON, the axis moves at the rapid traverse feedrate.
[Caution]
(1) Turning ON this signal in the automatic operation leads to an automatic operation pause.
(2) While this signal is ON, the "Automatic operation "start" command" signal is not valid.
(3) When the automatic operation is carried out with the manual speed command, the "In automatic operation "pause""
signal is output regardless of the axis movement.
(4) The manual speed command makes the movement follow the command on the 1st axis, even though the other axis is
commanded in the program. Any commands to the other axes lead "M01 OPERATION ERROR 0005" (Internal inter-
lock axis exists).
(5) The following G commands or modal make the movement different from that in the normal automatic operation. G00:
The manual feedrate is applied, not the rapid traverse feedrate.
G28: The manual feedrate is applied, not the reference position return feedrate. G31: The manual feedrate is applied,
not the skip feedrate. The movement when the skip signal is input, however, is the same as in the normal operation.
G33, G34 to 36 (L system): The thread cutting (G33), the variable lead thread cutting (G34: L system only), and the
arc thread cutting (G35/36: L system only) operate in the same manner as the dry run. The manual feed rate is
applied.
(When the parameter "#1247 set19/bit1" is set to "1", it operates according to the program command.) G95: The feed
per rotation operates the same as the dry run.
F1-digit feed: The manual feedrate is applied, not the F1-digit feedrate. The "F1-digit commanded" signal is not out-
put, either.
(6) Only the 1st handle is used. The other handles are ignored.
(7) When this signal is valid, the feedrate is not changed by the Inch/Metric changeover command (G20/G21), nor by the
rotary axis command speed tenfold.
(8) The manual interruption and the thread cutting cycle retract are available when this signal is ON. The automatic han-
dle interruption, as well as the manual operation in the manual/auto simultaneous mode, cannot be used on the 1st
axis because the axis applies the manual input upon this signal.
