WARNING
MESSAGE
WARNING
CODE
DESCRIPTION RECOMMENDED ACTIONS
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).
Rec HS Sensor 201 While Running, the drive has detected a
missing temperature sensor connected to
the TFB on the rectifier heatsink. A missing
sensor can result in either a Fiber Optic
Loss fault or a Sensor fault because a
missing sensor can be interpreted as either
0°C or over 100°C, and both are unrealistic
values.
– Verify sensor is completely seated
properly on TFB.
– Measure sensor resistance.
– Replace if necessary.
– 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 ChB Sensor 202 Not normally used: While Running, the
drive has detected a missing temperature
sensor connected to the optional TFB
connected to the fiber optic receiver RX7 on
FOI-L-B. A missing sensor can result in
either a Fiber Optic Loss fault or a Sensor
fault because a missing sensor can be
interpreted as either 0°C or over 100°C, and
both are unrealistic values.
Reg in Limit 51 Either the Speed Regulator or the Flux
Regulator autotune test hit the regulator limit
and the results of the test are not valid.
– REFER TO THE POWERFLEX 7000
SERIES B MANUAL (CHAPTER 4 –
COMMISSIONING) ON AUTOTUNE
PROCEDURES, RESULTS, AND
ACTIONS
Slip Range 189 This warning appears when unusual values
for slip appear, indicating there is either an
error in data or an unusual motor. The rated
slip for this warning has to be > 10%, or <
0.01%
– Verify Motor Nameplate Data
– Contact the factory with the motor data
and the application information
Slave 0-7 OffL 348-355 Slave (0-7) DAN Communication Loss-
Master only – Slave is Off line.
Slave1 UV 113 The measured value V Slave1 Average
(P137) is less than Line Undervoltage Trip
(P167) as a percentage of 1/3 Rated Line
Voltage (P18), for the period set by Line
Undervoltage Delay (P168). – Verify the VSB connections and tap
settings, and check resistance of VSB
board – Megger board to confirm integrity
– Check TSN fusing
– Check actual voltage values on the
Terminal for each bridge and the total
line voltage
– Check for possible source voltage
supply problems
– Use Multimeter and Oscilloscope to
check voltages on the drive test points
Slave2 UV 114 The measured value V Slave2 Average
(P138) is less than Line Undervoltage Trip
(P167) as a percentage of 1/3 Rated Line
Voltage (P18), for the period set by Line
Undervoltage Delay (P168).
