<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 the specified signal, the specified number of pulses are output.
Interrupt mode is used for original point return motion, interrupt 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 detect command signals are both “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.
