Danfoss VLT AHF 005 Service Guide

4 Operator Interface and Drive Control
4.1 Introduction
Drives are designed with self-diagnostic circuitry to isolate
fault conditions and show messages that simplify trouble-
shooting and service. The operating status of the drive is
shown in real time. Virtually every command given to the
drive results in some indication on the local control panel
(LCP) display. Fault logs are maintained within the drive for
fault history.
The drive monitors supply and output voltages along with
the operational condition of the motor and load. When the
drive issues a warning or alarm, the fault is not always
within the drive itself. In fact, for most service calls, the
fault condition exists outside of the drive. Most of the
warnings and alarms that the drive shows are in response
to faults outside of the drive. This service guide provides
techniques and test procedures to help isolate a fault
condition whether in the drive or elsewhere.
Familiarity with the information provided on the LCP
display is important. More diagnostic data can be accessed
easily through the LCP.
