Chapter 7 - Troubleshooting the Impulse

This chapter covers common faults, their possible causes and remedies. Also include in this chapter are Impulse Limits Tables for a variety of operational parameters, e.g. the Acceleration/ Deceleration/Velocity Limits Table.

The Impulse drive detects and resolves fault conditions. Faults are signaled by either a steady red or flashing red LED on the front panel. A solid green LED indicates normal operation. Most faults are cleared by either 1) cycling power, 2) sending a RESET command via the serial port or configurable logic input, or 3) probing the motor if the LED is steady red.

Read the CAUTION below before troubleshooting your Impulse.

CAUTION!

•Always use caution when working with mechanical systems. Gears and screw-driven cylinders are capable of exerting tremendous force against an obstruction.

•Always ensure that power to your system is OFF before performing any mainte- nance activity, or making any connections or adjustments.

•Do not insert objects into the Impulse drive. High voltages could cause personal injury, and equipment could be damaged beyond repair.

•Do not open the Impulse drive. The factory warranty will be voided if the drive is opened.
