Diagnostics and Troubleshooting

Max Following Error

This fault is generated when the following error exceeds the following error limit (default following error limit is 0.2 revs). With PowerTools Pro you can change the Following Error Limit value or disable it on the Position view.

Travel Limit +/-

This fault is caused when either the + or - Travel Limit input function is active.

All “On”

This is a normal condition during power up of the drive. It will last for less than 1 second. If this display persists, call Technical Service at Control Techniques.

Diagnostic Analog Output Test Points

The DGNE cable was designed to be use with either an oscilloscope or a meter. The wires are different lengths to avoid shorting to each other. However, if signals do get shorted to GND, the drive will not be damaged because the circuitry is protected.
