If the application is using digital outputs to reflect the internal status of the drive, these can be monitored using parameter d8. The below describes the details of understanding the status of each of the digital outputs (labeled MO for the open collector output and 3A/3B/3C for the relay output on the control board terminal strip). In this example, the multi-function output MO is “ON” and the multi-function relay is “OFF” (note that the indication for the multi-function relay is an indication of whether or not the relay coil is energized).

(ON)

(OFF)

3A/3B MO

9.4 Reviewing Fault Status of the Drive

As noted in Chapter 6, the Display Group has an entry that designates if there is an active fault and will display the fault code associated with that fault. The fault codes are described later in this chapter. While displaying the fault code within the Display Group, you can press the enter key to display the frequency the drive was running at when the fault occurred. By pressing the up arrow one time, you can display the current the drive detected when the fault occurred. By pressing the up arrow again, you will display the drive status when the fault occurred.

Function Group 2 (H parameters) also contains the current fault along with a history of the previous 4 faults. These faults are located at parameters H1, H2, H3, H4, and H5. As with the fault memory in the Display Group, you can subsequently display the frequency, current, and status for each of these faults using the same procedure outlined in Chapter 6.

9.5Fault Codes

Fault codes indicate conditions within the drive that require immediate attention. The drive responds to a fault by initiating a coast-to-stop sequence and turning off the power to the motor.

The integral keypad provides visual notification of a fault condition by displaying the following:

•Fault code on the display. (See table 9.1 for the fault code descriptions.)

•Flashing STP/FLT LED
