A10: Logic Power Input
A10 is used to bring in the 24 Volt DC supply powering up the logic portion of the Power Brick Controller.
This power can remain on regardless of the main AC bus power, allowing the signal electronics to be active
while the main motor power is passive.
Caution
The 24 VDC logic power must always be applied before applying
main AC bus power.
The
24-Volt (±5%)
power supply unit must be capable of providing
5 amperes
per Power Brick Controller.
If multiple drives are sharing the same 24-Volt power supply, it is highly recommended to wire each drive
back to the power supply terminals separately. This connection can be made using a 22 AWG wire directly
from a protected power supply.
