Connecting the Motor

Never connect the motor to the driver when the AC power is on.
Secure any unused motor leads.
Never disconnect the motor while the AC power is on.
Never connect motor leads to ground or to a power supply.

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 the rated current to prevent overheating. Winding dia-
grams for both connection methods are shown below. NC
means not connected.

Eight lead motors can also be connected in two ways: series and parallel. As with six
lead motors, series operation gives you more torque at low speeds and less torque at high
speeds. In series operation, the motor should be operated at 30% less than the rated
current to prevent over heating. The wiring diagrams for eight lead motors are shown
below.
