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.

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).
