Dnc Operation Mode (Dnc); Mdi Operation Mode; Manual Return - YASKAWA MOTIONPACK-110 Descriptive Information

3.1.6. MANUAL FEED MODE (HANDLE) (Cont'd).
Simultaneous 1-axis or 3-axis handle operation can be selected by setting the
parameter #1002 D6. For simultaneous 1-axis handle operation, one handle is changed by
using the axis change signal (HX for the X axis, HY for the Y axis, or HZ for the Z axis).
For simultaneous 3-axis handle operation, the three handles may be operated
separately. In addition, only the handle of the axis specified by using the axis change
signal (HX for the X axis, HY for the Y axis, or HZ for the Z axis) can be made effective.
See 9.2.2.
3.1.7 DNCOPERATION MODE (DNC)
This mode is selected for the host computer to operate Motionpack-110 DNC.
Automatic operation under motion control is performed while travel data is being
received from the host computer.
3.1.8 MDI OPERATION MODE (MDI)
This mode is selected to operate automatically for programs which are in one block specified
from the CRT control station. The specified programs are not stored in the memory of
Motion module:
NOTE
This mode is available for Motionpack-100 with CRT control station, on
and after type JEFMC-H012.
3.2 MANUAL RETURN TO REFERENCE POINT
With the Motionpack-ll0 system, the machine reference point is used as the system reference
ponit, and the system can be brought to this reference point from various positions as
described below.
When the power is turned off, the reference point data is deleted, and it must be
reset after the power supply is turned on again. Usually, a pulse generator with a zero-point
pulse and a limit switch for indicating the reference point area are used to determine the
reference point.
The motion to return to the reference point is started when a JOG signal towards the
reference ponit (i.e., +JX or -JX) is turned on while an external reference return (ZRN)
signal is on in the JOG or RAPID mode.
When the machine returns to the reference point, it stops, the axis coordinate data
becomes "0", and a "return-to-reference point" signal (ZPX, ZPY, or ZPZ for X-, Y-, or
Z-axis, respectively) is output.
