Connecting the AC Power Input

The AC supply to the drive can range for 90 - 260 VAC RMS, 50 to 60 Hz, single or three
phase.

The AC input voltage is the most significant attribute of the AC input to affect the power that is
available from the drive. At lower AC inputs the DC bus voltage is reduced and therefore will
limit performance of higher voltage AC servo motors. As a general rule AC inputs of 120VAC
will permit continuous operation of AC inputs of 240VAC servo motors. It is wise to match as
closely as possible the AC input and the servo motor’s voltage rating.

We recommend installing a Tyco 10VR1 line filter if the AC line is noisy. For the most severe
conditions and to ensure UL compliance the following super filters are recommended:
For 120VAC: Leviton 51010-WM
For 220VAC: Leviton 51240-WM .

AMP has a number of servo motors designed to operate at both 120 and 240 VAC input
(

See recommended motor list

)

When available three phase input is recommended for its lower ripple on the DC bus voltage.
This saves wear and tear on the DC bus capacitors and spreads out the current on the AC
input rectifiers.

WARNING: Exceeding the DC Bus voltage of 367VDC may cause the internal regenera-
tion circuitry to activate. This may result in a drive fault or some cases can result in
drive failure.

24 Volt Controller Input (Keep Alive)

The BLUAC5 servo drives offer a 24 volt input that will supply “Keep Alive” power to the con-
troller section of the drive. AC power can be removed without shutting down the servo con-
troller. This function can be used to maintain motor position information. When AC power is
restored to the drive the servo motor can be re-enable and the original position reestablished.

When 24 volt input is present and the AC input is removed the drive will display a “U” error
code.
