About this Product
The 24 V Power Supply Option maintains drive control circuit power in the event of a main
power outage. As long as the control circuit has power, network communications and I/O
data remain operational. The 24 V Power Supply Option provides external power to the
control circuit only, and does not provide power to the main circuit of the drive.
It is possible to read fault and parameter data in the drive via the operator or network
communications when the drive switches to the 24 V Power Supply Option as a back-up
power supply.
Note:
Parameter settings cannot be changed without the power of the drive's main circuit, even though
the control circuit may have enough power to operate.
