CHAPTER OBJECTIVES
Chapter 6 provides information to guide the user in
understanding drive fault conditions and general
troubleshooting procedures for Bulletin 1305 drives. Included is
a listing and description of the various drive faults with
possible solutions, when applicable. Also included is a section
on general troubleshooting. (Refer to 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.
