DESCRIPTION RECOMMENDED ACTIONS
Parameter Range 88 A parameter was read from NVRAM or the
DIM, which was outside the valid range.
The parameter has been set to a default
value. The Linear # of this parameter has
been stored in "Parameter Error", under the
Feedback grouping.
– If this was a result of an INIT operation,
contact the factory
– If this was a result of a LOAD operation,
correct the parameter value and perform
a SAVE operation
– Check the settings on the DIM to
determine whether it is limiting the
paramter‟s max or min values.
Phantom Alarm 93 DEVELOPMENT ERROR - An unused bit in
the last 16 bits in either a fault or warning
word has been set and detected by the
Alarm Queue server. These bits are never
used in firmware. Either a used bit has
been overlooked in the Faults/Warnings
database, or the control is incorrectly setting
an alarm word.
– Noise/Grounding Issue
– Contact the factory
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 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.
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.
