8.4.5 Absolute Encoder Setup (Fn008)
Setting up (initializing) the absolute encoder is necessary in the following cases.
• When starting the machine for the first time
• When an encoder backup error alarm (A.81) is generated
• When an encoder checksum error alarm (A.82) is generated
• To set the absolute encoder multiturn data to 0
Use a built-in type digital operator in the SERVOPACK or a digital operator for setup.
1. Encoder setup operation is only possible when the servo is OFF.
2. If the following absolute encoder alarms are displayed, cancel the alarm by using the same method as the
setup (initializing). They cannot be canceled with the SERVOPACK alarm reset input signal (/ALM-
RST).
• Encoder backup error alarm (A.81)
• Encoder checksum error alarm (A.82)
Any other alarms that monitor the inside of the encoder should be canceled by turning OFF the power.

Note: The digit that can be set will blink.
4 Press the DATA/ENTER Key.
The display will be as shown at the left.
5 Continue pressing the UP Key until PGCL5 is displayed.
Note: If there is a mistake in the key operation, “nO_OP” will blink for
about one second. The panel operator or digital operator will
return to the utility function mode.
6 Press the DSPL/SET Key. This will clear the multiturn data of the
absolute encoder.
When completed, “donE” will blink for about one second.
