6.3 MANUAL OPERATION1 (Cent’d )
Operation in HANDLE Mode t
The control with HANDLE dial+ can permit the
operation described below.
(1) Set MODE SELECT switch to HANDLE.
(2) Select the axis with HANDLE AXIS switch.
(3) Select the move amount of the machine cor-
responding to one scale of HANDLE dial
using MANUAL PULSE MULTIPLY switch.
Metric:
0.001- 0,01- 0.1
(mm per graduation)
Inch:
0.0001- 0.001 - 0.01
(inch per graduation)
Note :
MX1OOOJ! or IIXI()()()O1! is regarded as
“X1OO.”
(4) Rotate HANDLE dial
Turning the dial clockwise:
The machine moves in the positive direction.
Turning the dial counterclockwise:
The machine moves in the negative direc-
tion.

Return to Reference Point
With an NC equipped with the stored lead-
screw error compensation or the stored
stroke limit functions,
either of the following
two reference point return motions must be
performed after switching on the power
supply and before starting automatic opera–
tion.
Manual return to reference point (See 5.2.1)
Execute G28 UO WO ; in the MDI mode.
This procedure is to teach the reference
point to the control,
since doing so is nec–
essary because both leadscrew error com–
pensation and stored stroke check are per-
formed with reference to the reference point
Checking Parameter #6006D 1, D 0
When the control is equipped with leadscrew
error compensation function or the stored
stroke limit function, set this parameter to
!ll .11
With the parameter #6006Dl, DO set to
!11 II
a return to the reference point is re-
quired before starting cycles, alarm codes
( 001 - 002 “reference point return incom-
plete” ) are displayed, if the CYCLE START
key is pushed without making a reference
point return immediately after turning on the
power supply.
Be sure to perform the man-
ual operation for return to reference point.
6.5 PREPARATIONS FOR AUTOMATIC
OPERATION
To start to operate the machine in the automatic
mode, the machine must be brought to the start
point, after the application of the power supply.
The panel operation required for this varies
with programs as shown below. For details,
refer to the operation manual of the machine
tool builder.
(1) When G28 (AUTOMATIC REFERENCE POINT
RETURN) is used
Where G 28 is written in the beginning of
the program, move the tool manually to a
point a short distance away from the refer-
ence point.
If the start point is on the side of the refer-
ence point from the traverse speed reducing
point, the NC causes overtravel when the
CYCLE START key is pushed.
EXAMPLE :
EOR ;
NOO1 G28 UO WO ;
NO02 G50 X.. Z.. . ;
(2) When MANUAL RETURN TO REFERENCE
POINT function is used
Where G28 is not programmed, and the coor-
dinate set up point is the reference point,
bring the tool manually to the reference
point before starting the automatic cycle
operation.
Refer to 5.2.1, “Manual Return
to Reference Point. ”
