MSSTAC6 Step Motor Drive User Manual
Note: NC = not connected
Eight lead motors can also be connected in two ways: series and parallel. As with six lead motors,
series mode will provide more torque at low speeds and less torque at high speeds. When connected in
series, 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.

Connecting to the PC using RS-232

Position the PC within 6 feet (1.83 meters) of the step drive.
Locate the black adapter plug that came with the drive. Plug the large end (9 pin connector) of the
adapter into the COM1 serial port on the PC. Secure the adapter with the screws. If the COM1 port is already
in use, the COM2 port may be used. If the COM2 port has a 25 pin connector and this port must be used,
purchase a 25 to 9 pin serial adapter. Another option is to use a USB port via a USB to RS-232 adapter.
Also included with the drive is a telephone line cord. Plug one end into the adapter just secured to the
PC and the other end into the drive's RS-232 jack. If the drive must be located farther from the PC, the cord
may be replaced by a longer one. Do not exceed 50 feet (15.24 meters).
Never connect a MSSTAC6 drive to a telephone circuit. It uses the same connectors and cords as
telephones and modems, but the voltages are not compatible.
