3.2.7
Reset Absolute Encoder (Fn008)
You must reset (initialize) the absolute encoder at the following times.
•
When starting the system for the first time
•
When an A.810 alarm (Encoder Backup Alarm) occurs
•
When an A.820 alarm (Encoder Checksum Alarm) occurs
•
When you want to reset the multiturn data in the absolute encoder
Note: 1. You cannot reset alarms from the SERVOPACK to clear the A.810 alarm
(Encoder Backup Alarm) or the A.820 alarm (Encoder Checksum Alarm).
Always use the operation to reset the absolute encoder to clear these alarms.
2. If an A.8
alarm (Internal Encoder Monitoring Alarm) occurs, turn OFF the
power supply to reset the alarm.
Preparations
Always check the following before you reset an absolute encoder.
•
The parameters must not be write-prohibited (Fn010 must be set to
0000).
•
The servo must be OFF.
