Precautions for Correct Use Precautions for Correct Use
After the absolute encoder is set up, the power supply to the OMRON 1S-series Servo Drive or
G5-series Servo Drive must be cycled. When setup processing for the absolute encoder is com-
pleted, an Absolute Value Clear Error (A27.1) will occur in the Servo Drive. Cycle the control
power supply to the Servo Drive to clear this error and complete the absolute encoder setup pro-
cedure.
Using an Absolute Encoder in Rotary Mode
If you set the Count Mode axis parameter to Rotary Mode, the actual position will be a ring-shaped
counter in the range between the modulo maximum position setting value and the modulo minimum
position setting value. When using an absolute encoder in Rotary Mode, the absolute encoder home
offset is automatically calculated and updated in the MC Function Module each motion control period.
The updated absolute encoder home offset is automatically saved to the non-volatile memory in the
NY-series Controller when the power supply to the Industrial PC is turned OFF. This enables recovering
the actual position of a rotating axis from the absolute encoder the next time power is turned ON even if
the power to the Industrial PC or Servo Drive is turned OFF.
