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.
