Control Techniques Commander CDE Trips: Troubleshooting
When a failure occurs with the CDE drive the display will flash a series of segment characters for the trip.
Example: tr iP OU
Commander CDE series stores the past ten failure codes in parameters #10.14 – 10.23 in trip number form. A numeric value trip code is a basic form of the symptom for the technician to work with. These past trips can be accessed via the keypad by entering the value of 149 in the keypad at parameter 00.
Scroll to menu 10, for parameter #10.14 to see a trip number.
Example: 6
Symptom explanations provide an avenue on how to analyze the drive for particular problems.
To make the troubleshooting process easier a chart was created to link the type of trip with the symptom.
