Chapter 3 - Connecting and Installing Your Impulse

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 that Step/Direction and Differential Jumpers are installed (see 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 controller should be wired to Step +, the Direction signal to Dir +, and the Shutdown 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.
