The consumption of the CD1-k amplifier is 320 mA with 24V
DC
. So, a 24 V / 30 A/h battery can keep the amplifier
under voltage during i.e. a long 3 days week-end. This backup method is very interesting for saving the machine
initialization as well as the axis position even when moving with mains switched off.

For a multiaxis application with n amplifiers, the circuit breaker rating is given by
the formula:
In = 0,3
Σ
n I rated amplifier
But, the ratings below must not be exceeded:
- 20 A on 230 V amplifiers,
- 20 A on 400 V / 1,8 to 14 A amplifiers,
- 40 A on 400 V / 30 A and 45 A amplifiers,
- 60 A on 400 V / 70 A and 90 A amplifiers.
