Chapter 2 Warning Messages
L Leakage Low 68 Indicates that the Autotune L leakage (P220) measured was
less than 0.10 pu. Verify the motor name plate data entered in
the drive.
• Refer to the Commissioning chapter in the PowerFlex 7000 Medium
Voltage AC Drives User Manual for autotune procedures, results and
actions.
L Leakage High 69 Indicates that the Autotune L Leakage (P220) measured was
greater than 0.35 pu. Verify the motor name plate data entered
in the drive.
L Magnetize Low 70 Indicates that the Autotune L Magn (P221) measured was less
than 1.00 pu, and Lm Rated (P131) will have to be tuned
manually. Verify the motor name plate data entered in the
drive.
• Refer to the Commissioning chapter in the PowerFlex 7000 Medium
Voltage AC Drives, User Manual for autotune procedures, results
and actions.
L Magnetize High 71 Indicates that the Autotune L Mag (P221) measured was
greater than 10.00 pu, and Lm Rated (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 of the line filter cap (P133) is either less
than 0.35 pu or bigger than 0.55 pu. Verify capacitor nameplate
data and compare with the drive and motor ratings.
• Verify the capacitor nameplate data and compare with information
entered in the drive for the 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 the check
resistance of VSB board. Megger the board to confirm the integrity.
• Check the TSN fusing.
• Check the actual voltage values on the terminal for each bridge and
the total line voltage.
• Check for possible source voltage supply problems.
• Check the input contactor status or if it is open.
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.
LiqCool Leakage 356 A converter, pump or DB coolant leak has been detected. • Look through all of the cabinets for evidence of leaks. If a leak is
found, identify source of leak and resolve the issue.
• Verify that all leak detection sensors are operating correctly.
X 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.
