Connecting the Motor
Never connect or disconnect 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. Wiring diagrams for both connection
methods are shown below.

Connecting to the PC
•Locate your computer within 6 feet of the Si3540.
•Your Si3540 was shipped with a black adapter plug. It has a telephone style jack
at one end and a larger 9 pin connector at the other. Plug the large end into the
COM1 serial port of your PC. Secure the adapter with the screws on the sides. If
the COM1 port on your PC is already used by something else, you may use the
COM2 port for the Si3540. On some PCs, COM2 will have a 25 pin connector that
does not fit the black adapter plug. If this is the case, and you must use COM2,
you may have to purchase a 25 to 9 pin serial adapter at your local computer store.
•Your Si3540 was also shipped with a 7 foot telephone line cord. Plug one end
into the adapter we just attached to your PC, and the other end into the PC/MMI
jack on your Si3540.
Never connect the Si3540 to a telephone circuit. It uses the
same connectors and cords as telephones and modems, but the
voltages are not compatible.
Programming Note: Always apply power to the Si3540 after the Si TM Programmer
software is running on your PC.

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 overheating. The wiring diagrams for eight
lead motors are shown below.
