4. Connect 220-Volt AC 3 Phase Power to the
α
Series Digital Amplifier
An AC line filter will reduce the effect of harmonic noise to the power supply; its use is
recommended. Two or more amplifiers may be connected to one AC line filter if its power
capacity has not been exceeded. Figure 2-6 shows how to connect the amplifier to the line filter.

Figure 2-7. Connecting the Servo Amplifier to the Line Filter and Power Source
Note
You must supply the cable for both the connections between the line filter and
the servo amplifier, and the connection between the line filter and the power
source. Use 4-conductor, 600V, 60°C (140°F), UL or CSA approved cable
between the line filter and the servo amplifier.
The gauge of wire used for connecting the line filter to the power source must be
sized, based on the circuit breaker between the power source and the line filter
and the number of servos connected to the line filter.
If a separate isolation transformer is used to supply AC power to the amplifiers, a line filter is not
required.

Connect the Machine Emergency Stop to the
α
Series Digital Servo
Amplifier
C. Pin 3 of connector
CX4, located on the bottom of the
α
Series (SVU) amplifier,
supplies +24 volts DC for the E-STOP circuit. Route this through the machine E-STOP
circuit so that there is +24 volts DC to pin 2 when
not
in E-STOP. If no E-STOP switch
is used this connection
must
be made with a wire jumper.
Note
You must supply the cable for this connection. Keyed connector plugs,
marked as connector X and terminal connector pins are included with the
amplifier package. You must install this connection as a switch or jumper for
the amplifier to operate.
