<Description>
• In the pulse generation mode, interrupt mode is enabled when this signal is “1” at the rising edge of the start signal.
In interrupt mode, after a change is detected in a specified signal, the specified number of pulses are output.
Interrupt mode is used for original point return motion, interrupt point positioning motion or manual operation
(infinite length).
Phase-Z signal detect command = “1”: The phase-Z signal is “ON,” after origin LS is turned OFF.
Interrupt position detect = “1”: Interrupt signal is “ON.”
(The level of phase Z signal and interrupt signal can be set by setting the control register.)
Command pulse is output while both detect command signals are “0.”
Example of phase-Z signal position detection
Start command
(PC == > MP2)
Positioning end
(PC <== MP2)
Command pulse zero
(PC <== MP2)
Phase-Z signal detect command
(PC == > MP2)
Origin LS
(external input)
Phase-Z signal detection
(PC <== MP2)
Phase-Z: level detection
(external input)
“1”
“1”
“1” “1”
“1”
“1”
ON OFF
Not accepted because
phase-Z detect command
is “0.”
Not accepted because
origin LS is “ON.”

Precaution:
The change-over between the origin returning speed frequency (fH) and origin returning creep speed frequency
(fL) is made by rewriting the target frequency register from the CPU module.
