Rockwell Automation 1336VT AC DRIVE 5-300AMP (2-160KW) PROGRAMMING MANUAL - Manual (Page 73)

Local and Serial Port Parameters
Firmware Version 2.01-3.01
Chapter 5
5-10
Parameters 86Ć89
Parameters 86-89 will store the last (4) faults that the drive has
encountered. These buffers will be implemented in a cascading mode, that
is when a different fault occurs, the following sequence will take place.
•
Fault Buffer 0 will store the new fault.
•
Fault Buffer 1 will store the fault from Fault Buffer 0.
•
Fault Buffer 2 will store the fault from Fault Buffer 1.
•
Fault Buffer 3 will store the fault from Fault Buffer 2.
–– But only when a different fault occurs. Fault buffers will not cascade if
the same fault occurs unless Parameter 86 has been programmed to zero.
Important: Parameters 86 and 4 will always display the same value.
Parameters 86 and 4 will display the last fault received by the drive with
one exception. Since Parameter 86 may also be programmed to store and
display 0, if only one fault has occurred, Parameter 4 will display the value
programmed into Parameter 86.
