WARNING
CODE
DESCRIPTION
RECOMMENDED ACTIONS
L Magnetize Low
70
Indicates that the Autotune L mag (P221)
measured was less than 1.00 pu, and L
magnetizing (P131) will have to be tuned
manually. Verify the motor name plate data
entered in the drive.
L Magnetize High
71
Indicates that the Autotune L mag (P221)
measured was greater than 10.00 pu, and L
magnetizing (P131) will have to be tuned
manually. Verify the motor name plate data
entered in the drive. Manually tune flux
regulator.

Line Cap Range
165
The calculated pu value (P133) of the line
filter cap is either less than 0.35pu or bigger
than 0.55pu. Verify capacitor nameplate
data and compare with the drive and motor
ratings.
–
Verify capacitor nameplate data and
compare with information entered in
drive for drive and motor ratings.
Line Loss
161
The drive has detected a loss of input
voltage from losing the frequency (PLL) lock
on the input voltage. This is designed to be
a faster method of detecting an
undervoltage. The drive responds to this
warning as it does to a Master UV warning.
–
Verify the VSB connections and tap
settings, and check resistance of VSB
board – Megger board to confirm
integrity
–
Check TSN fusing
–
Check actual voltage values on the
Terminal for each bridge and the total
line voltage
–
Check for possible source voltage
supply problems
–
Check input contactor status or it opens
Line Synch Loss
158
The drive has lost synchronization with the
incoming line voltage, and has announced a
Phase Lock Loop warning.
–
Capture the voltage waveforms from the
ACB test points and examine for
inconsistency
–
Verify the incoming voltage, input
contactor status, VSB and TSN fuses.
–
Verify that the drive power system is
properly grounded
–
Check for noise on the control power in
the drive
–
Check the grounding for all signal and
control wiring
–
Verify the Input Impedance parameter is
valid and retune if required
Liqd IO Config
(C-Frame Only)
21
The XIO card which was being assigned to
the Liquid Cooling System Faults Input is
not a card which can be used for this
purpose.
–
Select the proper slot containing the XIO
card which is compatible for Liquid
Cooling System Faults usage.
