Y12 Axis 1
Axis 2
Axis 3 Positioning
start OFF : No positioning
start request
ON : Positioning start
requested
•
Zero point return or positioning operation is started.
•
The positioning start signal is valid at the rising edge, and carries
out starting.
•
When the positioning start signal turns ON during BUSY, the
warning “start during operation” (warning code: 100) will occur.

Axis 1
Axis 2
Axis 3 Axis stop OFF : No axis stop
request
ON : Axis stop
requested
•
When the axis stop signal turns ON, the zero point return control,
positioning control, JOG operation and manual pulse generator
operation will stop.
•
By turning the axis stop signal ON during positioning operation,
the positioning operation will be "stopped".
•
Whether to decelerate or suddenly stop for each stop group can
be selected with " Pr.38 Stop group 1 sudden stop selection" to
" Pr.40 Stop group 3 sudden stop selection".
•
During interpolation control of the positioning operation, if the axis
stop signal for either axis turns ON, both axes will decelerate and
stop.

•
When the JOG start signal is ON, JOG operation will be carried
out at the " Cd.19 JOG speed". When the JOG start signal turns
OFF, the system will decelerate and stop.
Y1D PLC READY OFF : PLC READY
OFF
ON : PLC READY ON
(a) This signal notifies the AD75 that the PLC CPU is normal.
•
This is turned ON/OFF with the sequence program.
•
The PLC READY signal is turned ON during positioning
control, zero point return control, JOG operation and manual
pulse generator operation, except for in the peripheral device
test mode.
(b) When data (parameters, etc) are changed, the PLC READY
signal will turn OFF depending on the item. (Refer to Chapter 7.)
(c) The following processes are carried out when the PLC READY
signal turns from OFF to ON.
•
The parameter setting range is checked.
•
The AD75 READY signal [X0] turns OFF.
(d) The following processes are carried out when the PLC READY
signal turns from ON to OFF.
In this case, the OFF time will be 100ms or more.
•
The AD75 READY complete signal [X0] turns ON.
•
The operating axis stops.
•
The M code ON signal [XD to XF] for each axis turns OFF,
and "0" is stored in " Md.32 Valid M code".
(e) When parameters or positioning data (No.1 to 100) are written
from the peripheral device or PLC CPU to the flash ROM, the
PLC READY signal will turn OFF.
