Connection of servo amplifier βiSVSP
and power failure backup module
-72562-031
3. Detail of cable connection
Please refer to DESCRIPTIONS (A-53866-464) except for cables below.
(1) Detail of cable K94
For power source (DC24V) cable of power failure backup module
Specifications of the third party switching power supply
<1> Input voltage range
170 VAC to 264 VAC (continuous)
240 VDC to 373 VDC (in power failure backup operation, 1 min. max.)
* Some types of switching power supply cannot be driven continuously on DC
power and, therefore, the specifications of some of these types state that they
"cannot be driven on DC power". Even such types can be driven on DC power
if they satisfy the time requirement for power failure backup (1 min. max.).
<2> Output current
Depends on the current consumption of the device to be connected.
<3> Operation at and below the input voltage specifications
The state in which the input voltage is 0 VDC to 240 VDC may keep for a maximum
of one minute. Even in this case, the switching power supply must be free from
damage and no voltage exceeding the specification range tolerable by β
iSVSP,
CNC, PMC and others (24V+10%) may be output.
