WARNING
MESSAGE
WARNING
CODE
DESCRIPTION
RECOMMENDED ACTIONS
Iso Fn2 Cntr
330
Isolation Transformer Fan 2 contactor
– Isolation transformer Fan 2 status is
NOT HIGH while the drive asked the
contactor to be closed
Iso Fn1 Loss
331
Isolation Transformer Fan 1 Loss
– Drive looks for Fan 1 status or air
pressure. If any of this lost the drive give
this warning.
Iso Fn2 Loss
332
Isolation Transformer Fan 2 Loss
– Drive looks for Fan 2 status or air
pressure. If any of this lost the drive give
this warning.
IsoTx Air Filter
(A-Frame Only)
26
The Pressure sensed by the pressure
transducer in the integral Isolation
Transformer section (as a voltage) has
dropped below the value set in Pressure
Value Transformer Warning (P655).
– Verify fan rotation
– Blocked airflow in the filters / ducting (if
installed) – Clean as required
– Improper Warning settings – Verify
Pressure Value voltage level when
running with clear air flow
– Verify Alarm and Trip set-up procedure
was completed adequately and adjust as
necessary
– Verify for drives with external ducting that
there is sufficient air to the drive input
– Verify supply voltage to pressure
transducer, and confirm output is stable
IxoTx Fan On
328
Isolation Transformer Fan ON warning
– Isolation transformer Fan status is high
while it should be low.
L Comm Low
55
Indicates that the Autotune Lc (P217)
measured was less than 0.02 pu and the L
Commutation (P140) will have to be tuned
manually.
– REFER TO THE POWERFLEX 7000
SERIES B MANUAL (CHAPTER 4 –
COMMISSIONING) ON AUTOTUNE
PROCEDURES, RESULTS, AND
ACTIONS
L Comm High
56
Indicates that the Autotune Lc (P217)
measured was greater than 0.15 pu and the
L Commutation (P140) will have to be tuned
manually.
L Leakage Low
59
Indicates that the Autotune Ls (P220)
measured was less than 0.15 pu.
– REFER TO THE POWERFLEX 7000
SERIES B MANUAL (CHAPTER 4 –
COMMISSIONING) ON AUTOTUNE
PROCEDURES, RESULTS, AND
ACTIONS
L Leakage High
60
Indicates that the Autotune Ls (P220)
measured was greater than 0.30 pu.
L Magnetize Low
61
Indicates that the Autotune L mag (P221)
measured was less than 2.00 pu, and L
magnetizing (P131) will have to be tuned
manually.
L Magnetize High
62
Indicates that the Autotune L mag (P221)
measured was greater than 10.00 pu, and L
magnetizing (P131) will have to be tuned
manually.
Line Cap Range
124
In PWM rectifier drives, the calculated per
unit value of the Line Filter Capacitor
(P133), based on the values entered for
Line Capacitor kVAR (P15), Line Capacitor
Volts (P16), and Line Capacitor Frequency
(P32) is outside of the normal range of 0.35-
0.55pu.
– Verify capacitor nameplate data and
compare with information entered in
drive
