A. Connecting a Motor to the Impulse

Connecting an IDC Motor

The A+, A-, B+, and B- phase outputs power the motor windings.

Connect motor wires to the motor connector (supplied) and plug the wired connector into the drive. Drawings below provide color codes for IDC motors.

GND is internally connected to the earth pin on the power connector. This provides a convenient terminal for grounding the motor frame and a motor cable shield. Note: If the motor is mounted on a machine that is grounded, do not connect the motor to GND.

The two INTLK pins must be jumpered together on the motor connector to allow power to the motor.

CAUTION! Do not remove the motor connector from the Impulse drive while power is applied. Removing the connector while power is applied could damage the connector pins.

Do not extend the interlock jumper wire to provide protection for another connector interface. The interlock circuit is susceptible to trips caused by noise-pickup in cables (20 kHz switching).

Note: This is a high-impedance safety-interlock circuit. If the interlock wire breaks, or the connector is removed, the current to the motor is immediately stopped, the drive faults (latches) and the LED on the front panel of the Impulse will flash five times (see LED Diagnostics on p. 3-8).

Connecting a Non-IDC Motor

One of the Impulse drive’s more advanced features, Open Loop Stall DetectTM, is guaranteed only when matched with one of IDC’s S or P-series motors.

IDC’s S and P series motors have custom windings to provide optimum dynamic performance with the Impulse. If you use another manufacturer’s motor, refer to Non-IDC Motors in Chapter 6, Hardware Reference, for more information.
