(2)Battery replacement
When battery voltage drops to about 1.3V, servo drive will trip into “AL-19 (battery voltage is lower)”.
Although multiturn data exists, user should change battery Immediate, otherwise multiturn data will be lost
when battery voltage keeps dropping. Please change battery according to below steps:
a.
Please change battery when servo drive is POWER ON.
b.
After changing battery, reset servo drive by hold pressing “SET” key to clear “AL-19”.
c.
Repower on servo drive, if there is no abnormal situation, it means battery change succeeds.
Note: 1. When servo drive trips into AL-24(under voltage protection), servo drive can only be reset by setting
HOME.
2.If user wants to shield AL-24 alarm, please set So-38 to bxxx0, reset encoder alarm by So-43, and reset servo
drive by hold pressing “reset” key.
3.
So-43 is used to reset motor encoder when encoder alarm occurs. User must hold down RESET key to reset
keypad panel.
(3) Encoder overspeed protection
If AL-46 alarm occurs, So-43 is used to reset motor encoder.
