ACS 300 User’s Manual 73
Chapter 8 - Fault Tracing
This chapter describes the ACS 300 fault indications and fault
memory. It also explains how to trace faults.
Fault Indications The ACS 300 continuously monitors itself for faulty operation.
If a fault condition should arise, a fault indication is displayed,
the fault LED illuminates and the ACS 300 waits for the oper-
ator to acknowledge the fault before resuming operation.
Fault Resetting An active fault can be reset either by pressing the keypad
button, deactivating the Start input (DI1) or switching the input
voltage off for a while. When the fault has been removed, the
ACS 300 will resume normal operation. If the fault has not
been removed, the ACS 300 will trip again. For automatic
fault reset, refer to parameter RESTART # on page 61.
Note! If the Start command is active and the fault has
cleared, fault resetting starts the drive.
Some faults require you to cycle the power off and on once
before the fault can be cleared. Proper fault reset action is
given in “Fault Tracing” on page 74.
Fault Memory When a fault is detected, it is stored so that it can be reviewed
at a later date. The last three faults are stored on Page 1
parameter FAULT MEMORY.
Scrolling through the FAULT MEMORY does not erase the
FAULT MEMORY. The oldest fault indication is automatically
erased when a new fault occurs.
Note! Undervoltage fault is stored in FAULT MEMORY if the
fault occurs and automatic restart (RESTART #) is off. If the
automatic restart is on, the undervoltage fault is not stored in
the FAULT MEMORY unless the fault persists after restart.
