9.6.2 Battery Warning
This warning is issued when the battery power for keeping sensor data is lowered on the absolute encoder
(ABS-E) and absolute sensor (ABS-RII). A dot in the 7-segment LED will be lighted when the warning is
issued.
When the sensor data is lost due to low voltage of the battery, battery alarm “U” will be displayed. In this
case, replace the battery or execute encoder clear procedure (either from CN-1 or remote operator).
(Refer to 6.4, Encoder Clear Using Remote Operator for encoder clear procedure using remote operator.)
Battery warning is automatically canceled if the battery voltage becomes normal (The battery alarm is not
canceled unless the encoder clear or alarm clear procedure is executed).
9.6.3 Overload Warning
Prior to the overload alarm output, overload warning is issued.
1. Setting
1) Set Mode1-Page18 overload warning level (OLWL).
2) Available setting is ranged from 30% to 99%, when the overload alarm level is set at 100%.
3) When the overload warning level is set at 100%, the overload warning output will be invalidated.
4) Parameter setting being input by remote operator or PC interface for overload warning level will be
validated by turning off the Servo Amplifier control power once.
2. Overload warning output
1) When overload warning is effective (e.g. OLWL = 80%)

Note 1. Set alarm output sequence at Func2 Bit6 of Mode2-Page3.
When Func2 Bit6 = “0”, CODE is displayed, and when Func2 Bit6 = “1” , BIT is displayed.
Note 2. “0” and “1” in the alarm output are:
“0” = Output is short-circuit, “1” = Output is open, when Mode2 Page3 Func2 Bit7 = “0”
“0” = Output is open, “1” = Output is short-circuit, when Mode2 Page3 Func2 Bit7 = “1”.
Note 3. 7-segment LED displays a flashing “4”.
