When a manual operation mode input contact is closed during the
thread-cutting process in a part program, the automatic operation
mode is retained while the thread is being cut.
19.2.3 MANUAL RAPID TRAVERSE SELECTION
(RPD) INPUT
When the RPD input contact is closed while the control is in the
manual jog mode, manual feeding in the +X, -X, +Z and -Z direc-
tions is performed in the rapid traverse rate.
After power supply is input, JOG feed rate can be used as RPD feed
rate by parameter (#6009D3= 1) until reference point return for each
axis has been executed completely.
19.2.4 MANUAL HANDLE FEED AXIS SELECTION
(HX, HZ) INPUT, AND AUTOMATIC MODE HANDLE
OFFSET (HOFS) INPUT
(1) Manual Handle Feed Axis Selection (HX, HZ) Input
This is the input signal for selecting the motion axis for the
motion by the manual pulse generator, with a control provided
with a man-ual pulse generator. When the HX input contact is
closed and the HZ input contact is open, the motion takes place
along the X-axis. When the HZ input contact is closed and the
HX input contact is open, the motion takes place along the Z-
axis.
Notes :
1. When both the HX and HZ input contacts are closed or open, motion
cannot be obtained by the manual pulse generator.
2. When the control is provided with a pulse generator for simultaneous 2-
axis control, and when a manual step feed is intended, these input
contacts are not used.
(2) Automatic Mode Handle Offset (HOFS) Input
This input is for enabling motion control with the manual
handle even during the automatic operation mode (Tape mode,
MDI mode, memory mode) with a control provided with a
manual pulse gen-erator.
With this input, relative displacements caused by the
remounting of the workplaces during automatic operation can be
compensated.
When the HOFS input contact is closed, the motion control by
the manual pulse generator is effective even during the automatic
operation mode. However, during the exection of a positioning
command in the automatic operation mode, machine motion cannot
be controlled by the manual pulse generator.
The motion axis for the manual pulse generator motion control
is selected by the HX and HZ (manual handle feed axis selection)
input contacts. When the control is provided with a simultaneous
2-axis manual pulse generator, the machine can be moved simulta-
neously along the two axes.
The travel distance per step of the manual pulse generator is
determined by the MP1, MP2 and MP4 (manual handle
multiplication factor setting) input.
Notes :
1. In an alarm state (ALM or IER output contact is closed), automatic
mode handle offset motion is ineffective.
2. When the interrupt input (STLK) contact is closed, manual handle
mode motion is possible, but automatic mode handle offset motion is
not possible.
3. When executing automatic mode handle offset motion, parameter
#6022, DOand D, for HOFSX (X-axis motion) and HOFSZ (Z-axis
motion) must be set to 1.
4. When parameter HOFSMV (#6022D,) is set to 1, the automatic
mode handle offset motion can be applied only to the time during the
interpolation in the automatic operation modes.
19.2.5 MANUAL FEED AXIS DIRECTION SELECTION
(+X, -X, +Z, -Z) INPUT
These inputs specify the motion direction when the control is in the
manual jog mode or manual step feed mode.

Under other input conditions, axis motion is impossible, and
current axis motion is stopped after deceleration.
19.2.6 MANUAL HANDLE/STEP MULTIPLICATION
FACTOR (MP1 , MP2, MP4) INPUT
When the control is in the manual handle/manual step feed mode,
the motion distance per step is determined by these input signals.
