3 POSITIONING DEDICATED SIGNALS
(10) Home position return request signal (M2409+20n)
.........................Status signal
This signal turns on when it is necessary to confirm the home position address.
(a) When not using an absolute position system
1) This signal turns on in the following cases:
• Motion CPU power supply on or reset
• Servo amplifier power supply on
• Home position return start
(Unless a home position return is completed normally, the home
position return request signal does not turn off.)
2) This signal turns off by the completion of home position return.
(b) When using an absolute position system
1) This signal turns on in the following cases:
• When not executing a home position return once after system start.
• Home position return start
(Unless a home position return is completed normally, the home
position return request signal does not turn off.)
• Erase of an absolute data in Motion CPU according to causes, such
as battery error
• Servo error [2025] (absolute position erase) occurrence
• Servo error [2143] (absolute position counter warning) occurrence
• Major error [1203] or [1204] occurrence
• When the
"rotation direction selection" of servo parameter is
changed.
2) This signal turns off by the completion of the home position return.
CAUTION
When using the absolute position system function, on starting up, and when the Motion
controller or absolute value motor has been replaced, always perform a home position return.
In the case of the absolute position system, use the PLC program to check the home position
return request before performing the positioning operation.
Failure to observe this could lead to an accident such as a collision.
(11) Home position return complete signal (M2410+20n)
.......................Status signal
(a) This signal turns on when the home position return operation using the
servo program has been completed normally.
(b) This signal turns off at the positioning start, JOG operation start and manual
pulse generator operation start.
(c) If the home position return of proximity dog, dog cradle or stopper type
using the servo program is executed during this signal on, the "continuous
home position return start error (minor error: 115)" occurs and it cannot be
start the home position return.
