5.2 How to Perform an Absolute Reset
5.2.1 Absolute Reset Using PIO Signals
x ACON or PCON
* Refer to the operation manual for your controller for details on input signals.
(1) Supply the main power (24 VDC) to the controller and simple absolute unit.
(2) An absolute encoder error (2) alarm is output.
(3) Input a PIO alarm reset signal.
(4) Turn ON the PIO pause input.
Note) When a pause signal input is provided in the selected PIO pattern.
(5) Input a PIO servo ON signal.
Note) When a servo ON signal input is provided in the selected PIO pattern.
The SV lamp on the controller should illuminate in green.
(6) Input a PIO home return signal.
When the home return is completed, the SV lamp on the controller should illuminate in green.
(7) An absolute reset is executed upon completion of the home return (HEND ON).
* Alarm reset, servo ON and home return can also be performed from the teaching pendant or PC
software.
(Note 1) If the simple absolute unit is connected to ACON, before an absolute reset is performed, an
operation may be executed for a maximum of the lead length for magnetic phase detection.
(Note 2) When the controller is PSEL, perform an absolute reset using the PC software.
