YASKAWA SGDV-180A - Software and Parameters Setup; Yaskawa Servo Drive; Servo Drive Parameters:; Servo Drive Absolute Encoder Setup

We need Pn002.2 set to 0 (Factory setting). This will enable the SEN input to be used to send the encoder
position to the motion controller.
Setting up the absolute encoder is necessary in the following cases:
When starting the machine for the first time
When an encoder backup error alarm (A.810) is generated
When an encoder checksum error alarm (A.820) is generated
When initializing the rotational serial data of the absolute encoder
1. Precautions on Setup
Set up the encoder when the servo ON signal (/S-ON) is OFF.

Servo Drive Absolute Encoder Setup
The rotational data will be a value between -2 and +2 rotations when the absolute encoder setup is
executed. The reference position of the machine system will change. Set the reference position of the
host
controller to the position after setup.
If the machine is started without adjusting the position of the host controller, unexpected operation may
cause injury or damage to the machine. Take sufficient care when operating the machine.
Set up the absolute encoder with Fn008.
