UPS
DC 3.6 V ±10%; 1 mA
Battery
3.6 V; lithium
Lithium batteries are long-life batteries and can be stored for a long time. The
required capacity depends on the desired battery lifetime and the number of
connected motors. The battery is not included in the scope of supply and has
to be ordered separately.
●
Recommended battery type:
maxell ER6C; 3.6 V / 1.8 Ah
(The accessory SUP-E03-DKC*CS-BATTRY (mat. no.: R911295648)
contains this battery.)
●
Alternative battery types:
–
TADIRAN SL760, 3.6 V / 2.1 Ah
–
JAUCH ER17505, 3.6 V / 3.6 Ah
–
JAUCH ER34615 3.6 V / 19 Ah
To be observed for transport:
The alternative battery types have a relatively high content of lithi‐
um and are Class 9 hazardous material.
Selecting the battery capacity
1.8 Ah per drive
The base load resistance in the D-Sub connector has been adjusted to this
battery capacity. The lifetime of the battery depends on the On and Off times
of the drive; with a battery capacity of 1.8 Ah it is approx. 2 to 10 years.
Battery current per drive (encoder c base load current):
●
Drive Off: approx. 70 μA
●
Drive On: approx. 10 μA
Battery base load and battery ca‐
pacity
The D-Sub connector contains a base load resistance of 499 kΩ. The base
load resistance causes a standby current of 7 μA which has to flow with
3.6 V / 1.8 Ah for a lithium battery. This prevents the battery from aging pre‐
maturely and gives it a relatively long service life.
If you use a bigger battery (> 1.8 Ah) at one D-Sub connector only, connect
an external resistor at the 4-pin spring terminal so that a higher standby cur‐
rent flows.
How to calculate the external resistance (R
ext
):
R
ext
= 3.6 V / I

I
ext
= [battery capacity / 1.8 Ah] × 7 μA - (7 μA × number_connectors)
Examples
●
1 D-Sub con battery 1.8 Ah ⇒
No additional base load resistance required
●
1 D-Sub con battery 3.6 Ah ⇒
Additional base load resistance of 499 kΩ required
