Fault Legend Description
17547 95559 30023 Overspeed OS – Motor overspeed. Motor speed
exceeded overpspeed level set by
inverter parameters F1-08, F1-09. Yes Yes Yes Minor Major Check for correct tach (encoder) PPR
value in inverter parameter F1-01.
May have excessive noise on encoder
signal inputs to Smart Trac AC1
drive. Consult MagneTek about
specifications of user-supplied
encoder. Major fault declared only if
inverter parameter F1-03
≠ 3, else a
minor fault.
17548 95560 30024 Speed Deviation DEV – Speed deviation. Difference
between speed reference and speed
feedback exceeded the deviation
level set in inverter parameters F1-
10, F1-11. Yes Yes Yes Minor Major Decrease load, increase
acceleration/deceleration times, or
increase deviation levels found at
inverter parameters F1-10, F1-11.
The input labeled ‘Major’ will be set
only if inverter parameters A1-02 = 1
or 3, and d5-01 = 0, and F1-04
≠
3.
17549 95561 30025 PG Open PGO – PG cable wires are
disconnected, bad tach, tach is not
connected to motor, or missing tach
power supply. This is actually a
tach loss condition. Yes Yes Yes Minor Major Connect wires from the Smart Trac
AC1 PG card to encoder, or look for
damaged wires. The input labeled
‘Major’ will be set only if inverter
parameters A1-02 = 1 or 3, and d5-01
= 0, and F1-02
≠
3.
1754A 95562 30026 Input Pha Loss PF – Inverter input phase missing.
Incoming power supply has an open
phase, or a large imbalance exists
between L1, L2, and L3. Yes Yes Yes Minor Major Check input AC supply. Note:
inverter parameter L8-05 = 1 enables
this fault.
