(Example) From Monday to Friday ; charge for 8 hours per day, discharge for 16 hours,
Saturday and Sunday ; use with discharge
1) If the upper limit setting for the number of encoder revolution is 800 [PRM];
Full charge amount : 24 [h] *5 [day] = 120 [h]
Total charge amount : 8 [h] *1.6 [h] *5 [day] = 64 [h]
Total discharge amount : 16 [h] *5 [day] + 48 [h] = 128 [h]
→
Assuming a start with full charge on Monday, it is necessary to fully charge the battery
every 10 days.
2) If the upper limit setting for the number of encoder revolution is 400 [PRM];
Total charge amount : 8 [h] *3.3 [h] *5 [day] = 132 [h]
Total discharge amount : 16 [h] *5 [day] + 48 [h] = 128 [h]
→
It is not necessary to have a continuous full charge if starting on Monday.
4-hour charge is stored every week. The upper limit is the reference value for the
retaining duration after fully charged.
7.2.3 Absolute Battery Voltage Drop Detection
Error detection (Alarm Output *ALM
(Note 1)
Signal gets turned off starts to be conducted when the
voltage of the absolute battery gets low.
Note 1 *ALM are the signals of active low.
After the power is supplied to the controller, they are usually on and turned OFF when
an error is detected.
If the alarm is generated, it will be necessary to absolute reset after the battery
replacement.
