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
• When the multiturn data of the absolute encoder is to be 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.
