B--65245EN/02
HANDLING
44
(1) Mode selection signal MD1, MD2, and MD4
[Classification]
Output signal <Yy+0#0 to #2> (common to both the peripheral
equipment control and direct command interfaces)
[Function]
This signal selects an operation mode.
[Operation]
The signal is a code signal consisting of three bits: MD1, MD2, and
MD4. The code signal selects one of three modes: automatic
operation (AUTO), handle feed (HANDLE), or jog (JOG), according
to the combination of these bits.
MD1 MD2 MD4 Description
1 0 0 Automatic operation (AUTO)
0 0 1 Handle feed (HANDLE)
1 0 1 Jog feed by +X and --X (JOG)
CAUTION
Do not switch the operation mode during automatic
operation. Stop automatic operation before switching the
operation mode.
NOTE
See Chapter 5 for details of handle feed.
(1) Feed axis and direction selection signals +X and --X
[Classification]
Output signal <Yy+0#4, #5> (common to both the peripheral
equipment control and direct command interfaces)
[Function]
These signals select the direction in which jog feed movement
(rotation) is to be performed, and cause it to be performed in the
selected direction.
[Operation]
The signals are valid when jog feed (JOG) mode is selected. They
indicate the direction of feed. Afte r JOG mode is se lec ted, changing +X
or --X, whic heve r is de sired , from 0 to 1 ca use s a nd keeps movement in
the corre sponding direction at a fee dr ate specified by the override signals
*OV1 to *OV8 ((1) of Section 2.3.7) or the manua l rapid trave r se
selec tion signal R T ((2) of Section 2.3.7), provided the signal is 1.
CAUTION
1 Simultaneously setting +X and --X to 1 results in neither
directio n being selected (equivalent to when both are 0).
2 If a feed axis selection signal becomes 1 before the jog feed
signal (JOG) is selected, these signals are ignored. If the
JOG signal is selected, it must be reset to 0 before the feed
axis selection signal is set. The servo amplifier unit begins
feeding when the JOG signal rises.
