6.5 Input Power
CAUTION!
Voltage above the absolute
maximum can result in
permanent damage to
the ACS internal drive
components.
WARNING!
Do not reverse bias the
power inputs. Doing so
will result in permanent
damage to the drive.
WARNING!
Do not short circuit the
motor power at the power
connector. Doing so may
damage the drive power
electronics. The motor/
cable is part of the current
regulation circuitry. For a
short occuring in a motor,
the motor leads should
provide enough resistance
and inductance to prevent
dangerous peak currents
from occurring.

1
Drive will shut down at 30V; any voltage above the absolute max voltage can result in permanent
damage.
2
Drive will turn off below 18V.
The drive and logic (keep alive) power share the same ground. Drive logic circuitry
can be powered from the keep alive input or the main drive power.
