WARNING
CODE
DESCRIPTION
RECOMMENDED ACTIONS
Pump Failure
(C-FRAME ONLY)
143
The drive has detected a fault from one of
the pumps in the cooling circuit.
– Verify the Pump O/L settings and
conditions
– Verify the Pump Control Relay status
and auxiliary contact signals.
Queues Cleared
91
This means that the drive had to clear the
fault and warning queues after an upgrade
of the firmware
– This was an issue because the memory
structure changed in 3.xxx firmware
– No action is required
R Stator High
52
Autotune Rs (P219) measured during the
autotune test was higher than 0.20 pu,
indicating the presence of extremely long
motor leads.
– REFER TO THE POWERFLEX 7000
SERIES B MANUAL (CHAPTER 4 –
COMMISSIONING) ON AUTOTUNE
PROCEDURES, RESULTS, AND
ACTIONS
– Ensure motor windings are connected
properly.
Rec Gate Pwr
205
Rectifier Gate driver power supply warning
– The device feedback was not right due
to the power loss in the gate driver
board. This may not only 20VDC PS
problem to SGCT but it can also be on
PS problem on gate driver card.
– This warning can come due to device
failure or device online diagnostic
Rec Heatsink FO
203
While Not Running, the Fiber Optic signal
from the TFB on the Rectifier Heatsink,
connected to Channel A fiber optic receiver
RX7 on FOI-L-A is not present. This is only
a fault while not running. If this occurs while
running it will appear as a warning.
– Check TFB and FOI board for power
– Check the Fiber Optic cables are
properly seated in the transmitters and
receivers
– Check the fiber optic cable for kinks,
bends, breaks that could be blocking the
signal
– This can occur if the sensor is not
connected to the TFB
– NOTE: This is a warning because the
drive should not fault on the loss of the
signal while running. There is no
imminent danger to the drive, but the
user needs to be aware that there is a
temperature feedback signal missing.
Rec ChannelB FO
204
Not Normally Used: While Not Running, the
Fiber Optic signal from the optional TFB
connected to Channel B fiber optic receiver
RX7 on FOI-L-B is not present. This is only
a fault while not running. If this occurs while
running it will appear as a warning.
Rec Heatsink OT
121
The temperature detection on the Rectifier
Heatsink, connected to Channel A fiber optic
receiver RX7 on FOI-L-A, has exceeded
Rectifier Heatsink Temperature Warning
(P112).
– Confirm actual temperature in
parameters is not higher than the
warning value – If so, investigate the
conditions of the drive (ambient / loading
/ elevation / ventilation/ filter status /
heatsink clogging)
– Check TFB and FOI board for power
and fiber optic integrity
– Check the sensor and temperature
offline (ambient) for accuracy
Rec ChannelB OT
122
Not Normally Used – The temperature
detection on a Rectifier Heatsink, connected
to fiber optic receiver RX7 on FOI-L-B, has
exceeded Rectifier Temperature Warning
Channel B (P526).
