Chapter 2 Warning Messages
PFC Disabled 214 The power factor compensation feature has been automatically
disabled. This feature is disabled under the following
conditions:
• During dynamic braking
• During over speed operating conditions
• During sync/de-synch period
• If line filter capacitor per unit is equal to or greater than 0.55
pu
• When operating in an autotune function the feature (will
not be used however will remain enabled)
• When using the ‘Standard’ option and running up to 50%
speed for 30 minutes
• When using the ‘Standard’ option and commanding a speed
greater than 50% where the drive is running in SVM for 5
minutes
• When HPTC mode is enabled
• Read the description to understand why this feature could have
been disabled.
• Contact MV Product Support.
PFC IdcLimit 227 Maximum DC current limit for power factor compensation has
been reached.
• No further power factor correction is possible under these
conditions.
• Check the drive load, speed, line and motor voltage.
• Contact the factory.
PFC Flux Limit 228 Flux command has been limited to avoid high motor voltage or
current.
• The power factor cannot be compensated further.
• Check the drive load, speed, line and motor voltage.
• Contact the factory.
Phantom Alarm 102 Development error: An unused bit in fault/warning word has
been detected. It is due to noise interference on the control
boards. Contact the factory.
• Check for a noise/grounding issue.
• Verify all board connections.
• Contact the factory.
Process Var Loss 229 Feedback from the process is not valid. • Check the process sensor, 4…20 mA or 0…10V input to the drive.
• Check the wiring at interface module (IFM).
X Pump Failure
(C-FRAME ONLY)
33 This warning is for liquid cool drives. The drive has detected a
pump failure in the cooling circuit.
• Verify the pump overload settings and conditions.
• Verify the pump control relay status and auxiliary contact signals.
Queues Cleared 100 The drive cleared the fault and warning queues due to a
firmware upgrade.
• No action is required.
R Stator High 61 Autotune R stator (P219) measured during the autotune test
was higher than 0.50 pu, indicating the presence of extremely
long motor leads.
• Refer to the Commissioning chapter in the PowerFlex 7000 Medium
Voltage AC Drives User Manual for autotune procedures, results and
actions.
• Be sure the motor windings are connected properly.
RAM Battery Low 166 The battery power on the NVRAM is low. • Save the parameters in the drive terminal and replace the battery.
Rec AC Cur Gain 174 The current gain calculated for DC link current sensing is lower
than expected.
• Verify that the HECS ratio and burden resistor match the drive/
motor ratings.
