2. Product Overview
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:
Parameter settings cannot be changed without drive main circuit power regardless of
whether the control circuit has enough power to operate.
