2.14 Backup
When you need to keep the drive electronics powered up during mains losses, for example to
maintain the simulated encoder function, certain precautions are necessary.
A)
Use an external 24Vdc / 2 A regulated power supply with protected output. Connect the
positive pole to 8-X3 (+Vbackup) and negative pole to 9-X3 (-Vbackup).
B)
Set b99.8 = 1 to programme the automatic undervoltage alarm reset (when the mains voltage
is restored).
Furthermore is not required to write in the pico-PLC the programme described in the example 11 -
“Examples and applications” chapter.
