4.7.4 Absolute Encoder Setup and Reinitialization
CAUTION
• The rotational data will be a value between -2 and +2 rotations when the absolute encoder setup is exe-
cuted. The reference position of the machine system will change. Set the reference position of the host
PC or PLC...etc to the position after setup.
If the machine is started without adjusting the position of the host PC or PLC...etc, unexpected operation
may cause injury or damage to the machine. Take sufficient care when operating the machine.
Setting up and reinitialization of the absolute encoder are 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
Set up the absolute encoder with Fn008.
(1) Precautions on Setup and Reinitialization
•
The write prohibited setting parameter (Fn010) must be set to Write permitted (P.0000).
•
Set up or reinitialize the encoder when the servomotor power is OFF.
•
If the following absolute encoder alarms are displayed, cancel the alarm by using the same method as the set
up (initializing) with Fn008. They cannot be canceled with the DRIVER Clear Warning or Alarm com-
mand (ALM_CLR).
•
Encoder backup error alarm (A.810)
•
Encoder checksum error alarm (A.820)
•
Any other alarms (A.8
口口
) that monitor the inside of the encoder should be canceled by turning OFF the
power.
(2) Procedure for Setup and Reinitialization
Follow the steps below to setup or reinitialize the absolute encoder.
This setting can be performed using the Write Memory command (MEM_WR). For details, refer to
