Applied Motion 3540M - Manual (Page 4)

You must now decide how to connect your
motor to the drive.
Four lead motors can only be connected
one way. Please follow the sketch at the
right.
Six lead motors can be connected in
series or center tap. In series mode, motors
produce more torque at low speeds, but
cannot run as fast as in the center tap configuration. In series operation, the motor
should be operated at 30% less than rated current to prevent overheating. Wiring
diagrams for both connection methods are shown on the next page. NC means not
connected to anything.

Connecting the Power Supply
If you need information about choosing a power supply, please read
Choosing a
Power Supply located on page 12 of this manual. The PS430 from Applied Motion
Products is a good supply for this drive.
If your power supply does not have a fuse on the output or some kind of short
circuit current limiting feature you need to put a 4 amp fast acting fuse between the
drive and power supply. Install the fuse on the + power supply lead.
Connect the motor power supply + terminal to the driver terminal labeled "+ VDC".
Connect power supply Ð to the drive terminal labeled "VDC Ð". Use no smaller
than 20 gauge wire. Be careful not to reverse the wires. Reverse connection
will destroy your driver, void your warranty and generally wreck your day.
Connecting the Motor
Warning: When connecting the motor to the driver, be sure that the
motor power supply is off. Secure any unused motor leads so that they
can't short out to anything. Never disconnect the motor while the drive
is powered up. Never connect motor leads to ground or to a power
supply!
The amplifiers in the drive generate heat. Unless you are running at 1 amp or
below, you may need a heat sink. To operate the drive continuously at maximum
power you must properly mount it on a heat sinking surface with a thermal constant
of no more than 4
°
C/watt. Applied Motion Products can provide a compatible heat
sink. Often, the metal enclosure of your system will make an effective heat sink.
Never use your drive in a space where there is no air flow or where other devices
cause the surrounding air to be more than 70
°
C. Never put the drive where it can
get wet or where metal particles can get on it.
Mounting the Drive
You can mount your drive on the wide or the narrow side of the chassis. If you
mount the drive on the wide side, use #4 screws through the four corner holes. For
narrow side mounting applications, you can use #4 screws in the two side holes.
