“Do’s, Don’ts and Important Notes”
∙NEVER connect or disconnect motor wires while power is supplied.
∙When using a 6 lead motor be sure to insulate/isolate unused wires.
∙The physical direction of the motor with respect to the direction input will depend on the connection of the motor windings. To reverse the direction of the motor with respect to the direction input, switch the wires on phase 1 or phase 2 of the outputs.
**************** WARNING ********************
LIVE CONNECTING/DISCONNECTING MOTORS WILL CAUSE DAMAGE THAT IS NOT COVERED BY WARRANTY.
Serial Interface (J2, J3)
Two (RJ-45) connectors provide a loop-through connection, facilitating multiple axis systems. This “mini- drop” network allows for a single ASCII character “name” to be assigned and stored in the integral non- volatile memory of each axis during the setup procedure.

All signals on J2 and J3 are interconnected; the 5-volt power is only supplied to J2 – 7. The 5-volts is intended to power an AMS serial adapter.
There are three types of serial adaptors available.
1.SIN-7 (DB-25), SIN-9 (DB-9). These are passive adapters that allow a basic RS-232 interconnect, suitable for single axis usage. Party line is not possible with the SIN-7 or SIN-9. Daisy chain protocol is possible but not recommended.
2.SIN-8 (DB-25) includes an RS-232 to RS-422 converter. A switch selects single or party line mode for up to 32 axes (includes terminator plug). Proper handshake must be implemented in your computer for successful party line operation.
3.SIN-10 (DB-9) is a microprocessor-based adaptor that features a dual UART, RS-232 to RS-422 converter at different baud rates and character buffers. The necessary handshake is built in, thus the sometimes expensive and time -consuming software interface is avoided. The serial communications is full duplex at 9600 baud. Operation at special 470k baud is possible.
If you have not chosen the SIN-10, the proper handshake MUST be implemented in the host computer to avoid loss of characters. This protocol is “echoed” characters. If your operating system or application software is not capable of character-by-character transmission, a SIN-10 is probably necessary. If system production cost is the priority, the additional system programming effort to implement a SIN-7, 8 or 9 may be cost effective. A complete description of the serial interface specifications and operation is contained in Section 2, “Serial Interface.”
