24VIN
24V auxiliary power input
When the drive uses AC power input to the RST terminal, all
functions of the drive work normally. When the above power
supply at the input side of the drive is forced to be cut off due
to the supply end, the drive is powered off and shut down.
Some functions can continue operate through the 24V
auxiliary power input, as follows:
1. All communication cards work normally
2. Parameters and be read, written, and copied through
keypad, RS-485, USB and communication cards.
3. Keypad is able to display and operate normally
