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 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 option as a back-up power supply.
Note: 1.
Parameter settings cannot be changed without drive main circuit power regardless of whether the
control circuit has enough power to operate.
2.
When connecting the 24 V Power Supply Unit, set the drive Undervoltage Detection Level (Uv) to its
default value.
