Connect the motor, feedback, and AC Power cables as shown in the following Connection Diagram but do not apply the AC Power at this time. It is highly recommended that Pacific Scientific motor and feedback cables be used during setup since improper cabling is the number one cause of start up problems. The RS-232 cable made by Pacific Scientific (order number CS-232-5600) can be used to connect the 9 pin serial port socket on the PC830 to the PC. If this cable is unavailable, a simple 3 wire cable can be made using the wiring diagram shown on page 2-6.

If you are using the drive’s +24 Vdc supply, connect I/O RTN (J2-38) to +24 VDC output RTN (J2-39). The last connection needed is to provide the hardware enable to the PC830 via J2-37 and +24V on J2-40. Preferably connect a toggle switch between J2-37 and J2-40. If a toggle switch is not available a clip lead that can connect or not connect J2-40 to J2-37 will do.

Most PLCs operate with a 16-bit word, the term word being used for the group of bits constituting some information. This allows a positive number in the range 0 to +65 535, i.e. 1111 1111 1111 1111, to be represented or a signed number in the range –32 768 to +32 767 in two’s complement, the most significant bit then representing the sign. Such signed numbers are referred to as integers with the symbol INT being used with inputs and outputs in programs of such 16-bit words. The term SINT is used for short integer numbers where only 8-bits are used, such numbers giving the range –128 to +127.

The term DINT is used for double integer numbers where 32 bits are used, such numbers giving the range –231 to +231 – 1. LINT is used for long integer numbers where 64 bits are used, such numbers giving the range –263 to +263 – 1. Where numbers are not signed the symbols UINT, USINT, UDINT and ULINT are used with integers, short integers, double integers and long integers.

Decimal fractions are referred to as real or floating point numbers, being represented by the symbol REAL for inputs and outputs in programs. These consist of two 16-bit words and so we might have 1.234567E+03 for the number 1.234 567 × 10+3, the E indicating that the number that follows is the exponent. The term LREAL is used for long real numbers where 64 bits are used.
