10-4 Setting for Low Battery Voltage and Replacement of Lithium Battery
This section describes the handling of "ABS encoder battery alarm" (830) and "ABS encoder battery warning" (930)
after absolute position system is set.
Settings of Encoder Battery Alarm/Warning
Life of the lithium battery with battery case (SV-B1) is about 20000h when power off, ambient temperature is 25°C.
When lithium battery voltage drops to below 2.7V, "ABS encoder battery alarm" (830) or "ABS encoder battery
warning" (930) will occur by setting "*Low battery voltage" (ALM_05) .
Switching of alarm, warning may be set via parameter setting.
*1 When "Alarm" is selected, after control circuit is ON and "Alarm (ALARM)" output is OFF, battery voltage will be
monitored for only 4 seconds. After this, no monitoring is performed.
*2 When "Warning" is selected, after control circuit is ON, the battery voltage is always monitored.
