14.2 Manual Speed Command
 The feedrate is set as follows depending on the manual mode:
- In the handle mode
The feedrate of the 1st handle's 1st axis * program command speed ratio
(The handle magnification of the smallest number's part system across the part systems that the manual speed com-
mand is enabled)
- In the JOG mode
Among the part systems in which the manual speed command is enabled, the JOG feedrate of the smallest number's
part system * program command speed ratio
- In the manual rapid traverse mode
Among the part systems in which the manual speed command is enabled, the 1st axis's rapid traverse feedrate of the
smallest number's part system * program command speed ratio
(Example) In JOG mode
- When the "manual speed command valid" signal of the 1st and 2nd part system is ON
Feedrate = JOG feedrate of the 1st system * program command speed ratio
- When the "manual speed command valid" signal is ON only for 2nd part system
Feedrate = JOG feedrate of the 2nd system * program command speed ratio
 The feedrate is limited by the following speed, whichever is slower:
- Program command speed * the setting value of #19005 (%)
- For the cutting command, the cutting clamp feedrate parameter (#2002 clamp) of each axis
For the rapid traverse command, the rapid traverse feedrate parameter (#2001 rapid) of each axis
 In the reverse run involving two or more part systems, once any of the part systems reaches to the block start, rest of the
part systems also stop.
(Example)
$1
G00 X100.
G01 X200. F1000
- When a reverse run starts at the second block $1:X120. $2:X170.
When $1 reaches X100. (block start), $2 stops at X150.
A reverse run operation is not applied to a part system that is executing the following types of commands/blocks; G code
with which a reverse run is prohibited (such as G33: thread cutting, G04: dwell), or an MSTB block (except for a timing
synchronization between part systems with M code).
(Example)
$1
G00 X100.
G33 X200.U0.F1.S600 F1000
- When a reverse run starts at the second block $1:X120. $2:X170.
In $1, the axis stops. (Reverse run impossible)
In $2, the axis moves to X50. (block start), then stops.
 For the rapid traverse (G0), the axis moves with the composite speed of the rapid traverse axis, and other than G0, the axis
moves with the ratio of the command speed across the part systems.
 The program command speed ratio is calculated as "S command value * command value F" of the program as the program
command speed. S command value is used in the commanded part system.
If S command is "0", the handle/JOG/manual traverse feedrate of the smallest number's part system in which the manual
speed command is valid is applied.
 If the program command speed is "0", the handle/JOG/manual traverse feedrate of the smallest number's part system in
which the manual speed command is valid is applied.
 During the forward run, the handle/JOG/manual traverse feedrate of the smallest number's part system in which the manual
speed command is valid is applied for thread cutting.
When the parameter "#1247 set19/bit1" is set to "1", the movement speed follows the program command for thread cutting
and the movement up to the end point of the next block in which the thread cutting is finished (the G33 mode has ended.).
When performing thread cutting in the 1st part system, the handle speed/JOG/manual traverse feedrate of the 1st part sys-
tem is applied to other part systems in which thread cutting is not being performed.
 If the manual speed command is executed in only one part system, the program command speed ratio becomes "1"; there-
fore, the handle speed/JOG/manual traverse feedrate of the executed part system is applied. It is possible to limit the fee-
drate with "Program F command speed * Setting value (%) of #19005".
