Fault Legend Description
17607 95751 30215 Alm: Overspd Det OS – Motor overspeed alarm. Motor
speed exceeded overpspeed level set
by inverter parameters F1-08, F1-
09. Yes Yes Yes Minor Minor 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. Alarm declared only if
inverter parameter F1-03 = 3.
17608 95752 30216 Alm: Spd Deviatn DEV – Speed deviation alarm.
Difference between speed reference
and speed feedback exceeded the
deviation level set in inverter
parameters F1-10, F1-11. Yes Yes Yes Minor Minor Decrease load, increase
acceleration/deceleration times, or
increase deviation levels found at
inverter parameters f1-10, f1-11.
Alarm declared if f1-04 = 3. The
input labeled ‘Minor’ is active only if
a1-02 = 1 or 3, AND d5-01 = 0.
17609 95753 30217 Alm: PG Open PGO – Alarm; No tach pulses
received when speed reference > 0
in time set by f1-14. This is the
same as a Tach Loss fault. Yes Yes Yes Minor Minor Check wires from the Smart Trac
AC1 PG card to encoder, faulty tach,
faulty tach power supply or look for
damaged wires. The alarm is
declared only if inverter parameters
a1-02 = 1 or 3, and d5-01= 0, and f1-
02= 3
1760A 95754 30218 Alm: Oper Disc OPR – Operator disconnected.
Digital operator has been
disconnected from drive while in
Run mode. Yes Yes Yes Minor Minor Reconnect digital operator to
inverter. Alarm is declared if o2-06=
0.
