WARNING

MESSAGE

WARNING

CODE

DESCRIPTION

RECOMMENDED ACTIONS

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

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).
