WARNING
CODE
DESCRIPTION RECOMMENDED ACTIONS
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 Factory
PFC Flux Limit 228 Flux command has been limited to avoid
high motor voltage or current.
– Power factor cannot be compensated
further.
– Check the drive load, speed, line and
motor voltage.
– Contact Factory
Phantom Alarm 102
DEVELOPMENT ERROR -
Unused bit in fault/warning word has been
detected. It is due to noise interference on
the control boards. Contact factory.
– Noise/Grounding Issue
– 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 IFM
Pump Failure
(C-FRAME ONLY)
33
This warning is for liquid cool drives. Drive
has detected a pump failure in the cooling
circuit. Verify O/L settings, control relay
status and aux contact signals.
– Verify the Pump O/L settings and
conditions
– Verify the Pump Control Relay status
and auxiliary contact signals.
Queues Cleared 100
This means that the drive had to clear the
fault and warning queues after an upgrade
of the firmware
– 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. Ensure motor windings are
connected properly.
– REFER TO THE POWERFLEX 7000
MANUAL (COMMISSIONING chapter)
ON AUTOTUNE PROCEDURES,
RESULTS, AND ACTIONS
– Ensure motor windings are connected
properly.
RAM Battery Low 166 The battery on the NVRAM is running low. – Save the parameters in the drive
terminal and replace the battery.
Rec Gate Pwr Sup 173 Rectifier Gate driver power supply warning
This warning is for SGCT based drives and
indicates a problem with the gate power
supply associated with a particular device
which is also likely in the warning queue.
– The device feedback was not correct due
to power loss to the gate driver board.
– This can be from the 20V DC output of the
IGDPS or on the gate driver board itself.
– This warning can also appear as a result of
another device fault such as an Online
Fault.
– This wanring can also come if the device
has failed.
