24 V Control Power Supply Unit
The 24 V Control Power Supply Unit 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 unit 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 unit 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.Parameter settings cannot be changed without drive main circuit power regardless of whether the control circuit
has enough power to operate.
