[7] Datum Position Move (RSTR, REND)
PIO signal
RSTR Signal is a command signal to move
(Note 1)
to the datum position * set at any point.
This command is processed at the startup (ON-edge) and operation to the datum position is
conducted.
Once the movement to the datum position is complete, output REND (datum position movement
complete) signal turns ON
(Note2)
.
For the absolute type actuators with no home-return operation conducted, have the position
management of the host controller conducted at this point.
* Set it in Parameter No. 167 only for the absolute type actuators.
Note 1 Movement to the datum position is made under the following conditions.
Pulse train datum position (Parameter No.167 setting position)
PIO jog velocity (Parameter No.26 setting position)
Note 2 REND Signal turns off under the following conditions.
1) RSTR signal is ON
2) When servo is OFF
3) ON-edge is detected due to one of the signals of compulsory stop (CSTP), home return
(HOME) or deviation counter clearing (DCLR).
4) Mode changed from AUTO to MANU
Caution
● Servo alarm will be generated when RSTR signal is turned ON while HEND is OFF.
● An alarm for DCLR Signal detection in the datum position movement command will be
generated if turning RSTR Signal gets turned on while DCLR Signal is on.
