F. Connecting Inputs and Outputs

Connect your inputs and outputs to IDC’s 961/962 Indexer according to the information below.

Schematics for Impulse I/O circuits can be found in Chapter 6, Hardware Reference

Application Notes

1. On 961/2, ensure t hat Step/Direction and Di fferent ial Jumpers are installed (s ee 961/2 manual).

2. If using IDC P/N SS-I/O or SS-I/O-6 cable, cut one end of the cable if necessary (see table

below for SS-I/O cable color-code). If making your own cable, or using a non-IDC indexer,

refer to the Impulse I/O Schematics (Chap. 6) and the 25-pin Connector drawing below.

3. Use a shielded cable, and connect the shield only at the Impulse. Connect shield to pin 9.

4. IDC offers a 25-pin screw-terminal breakout board (shown below) to add convenience and

flexibility to your application. Terminals on the breakout board match the pins of the 25-pin

connector on the Impulse.

5. When wiring TTL signals to other manufacturer’s indexers, the Step TTL command signals

from the control ler shoul d be wired to Step +, the Direction signal to Dir + , and the Shut down

signal to SD + (Step -, Dir -, and SD - should not be connected). Remember, the drive common

must be connected to the controller common.

6. Activating the Shutdown input disables the drive amplifier and de-energizes the motor. When

this input is OFF the drive is enabled and the motor is energized. The polarity of this input is

configurable.

7. The open-collector Fault Output turns ON (Active High) when any one of the LED- indicated

conditions occur (see Section E, LED Diagnostic Indicators). The output stays ON while the

LED flashes.
