Troubleshooting and Fault Information

Chapter

6

CHAPTER OBJECTIVES

Chapter 6 provides information to guide the user in understand-
ing drive fault conditions and general troubleshooting
procedures for 1305 drives. Included is a listing and description
of the various drive faults with possible solutions, when
applicable. General troubleshooting is presented in Table 6.C.

FAULT INFORMATION

Figure 6.1 Fault Display

Drives equipped with a Human Interface Module will display a
brief fault message on Line 1 of the LCD display when a fault
occurs. Line 2 of the display indicates the corresponding fault
number. Important: For Series A HIM software version 3.00
and Above or Series B HIM software version 1.01 and Above,
faults are displayed as soon as they occur. Earlier HIM versions
only display faults when the HIM is in the Status Display
Mode. [Fault Buffer 0] through [Fault Buffer 3] display
previous faults.

Table 6.A lists all faults numerically with a cross reference to
the page number where information can be found relating to
that fault. Table 6.B provides an alphabetized listing of the
faults with a description and possible corrective action to take.

Fault LED

All drives come equipped with a fault LED. When the fault
LED is illuminated it is an indication a fault condition exists.
Refer to page 2-3 for the location of the fault LED. Once the
fault is properly cleared the LED will return to an off state.

Diagnostics

As can be seen in Figure 2.3, there are two indicators provided
to display the drive’s status condition. The DC Bus Charge
Indicator is a neon bulb that will be illuminated when power is
applied to the drive. The Fault Indicator is an LED that will be
illuminated if a drive fault condition exists. Refer to details on
How To Clear a Fault, below.

How To Clear a Fault

Important: Resetting a fault will not correct the cause of the
fault condition. Corrective action must be taken prior to
resetting the fault.

To clear a fault perform one of the following:

1. Cycle power to the drive.

2. Cycle the stop signal to the drive.

3. Cycle the [Clear Fault] parameter. See page 5-39.

Important:The stop signal will not clear a fault if the [Logic
Mask]
or [Fault Mask] bit of that adapter has been disabled or
the [Fault Clear Mode] parameter is disabled.
