(5) Operation setting for incompletion of home position return
(a) Operation in selecting "0: Execute servo program"
1) Servo program can be executed even if the home position return request
signal (M2409+20n) is ON.
(b) Operation in selecting "1: Not execute servo program"
1) Servo program cannot be executed if the home position return request
signal (M2409+20n) is ON. However, the servo program can be
executed even if the home position return request signal (M2409+20n) is
ON in the case of only servo program of home position return instruction
(ZERO).
2) At the time of servo program start, when "1: Not execute servo program"
is selected in the operation setting for incompletion of home position
return and the axis which the home position return request signal
(M2409+20n) is ON exists also with one axis, a minor error [121] occurs
and the servo program does not start.
3) JOG operation and manual pulse generator operation can be executed
regardless of the home position return request signal (M2409+20n)
ON/OFF.
4) Same operation is executed regardless of absolute position system or
not. When "1: Not execute servo program" is selected in the case of not
absolute position system, the home position return request signal
(M2409+20n) turns ON at power supply ON or reset of Motion CPU and
power supply ON of servo amplifier. Therefore, it must be executed
home position return before a servo program start.
5) Same operation is executed in also TEST mode.
6) This setting is valid in the real mode only. Servo program can be
executed for a virtual axis connected to the output axis which the home
position return request signal (M2409+20n) is ON.
(6) Indirect setting of home position return data
A part of home position return data can be executed the indirect setting by the
word devices (D, W, #) of Motion CPU.
(a) Data devices for indirect setting
There are data registers (D), link registers (W) and Motion registers (#) as
data devices for indirect setting. (Word devices except data registers, link
registers and Motion registers cannot be used.) Usable devices are shown
below. (Set the number of words for 2 words as even number.)
Word devices Usable devices
D 800 to 8191
W 0 to 1FFF
# 0 to 7999
