7.6.4 EXTERNAL THERMAL PROTECTION (ETP)
Group of parameters number [802]
Setting the external thermal protection (ETP) evaluation block. Sensor type selection (PT100, PTC, Custom).
External temperature faults and warnings configuration. For proper operation of ETP, it is necessary to
properly configure the corresponding AOUTx and AINx in the [486] (page 48) group.

Description
Def.
ETP Type [792]
Turning on / off the external thermal protection (ETP) function and selecting the
connected temperature sensor type. Number of sensors connected in series is set
by the parameter Sensor count [793] (page 71).
ETP
turned
off
ETP turned off Inverter does not evaluate external temperature.
PT100
External temperature sensor is one or more PT100 sensors.
KTY83/85 1xx
External temperature sensor is one or more KTY 83/110, 83/120 or KTY 85/1, KTY 85/110,
85/120, 85/150 sensors.
KTY81/82 1xx
External temperature sensor is one or more KTY 81/110, 81/120, 81/150 or KTY 82/110,
82/120, 82/150 sensors.
Custom sensor
External temperature sensor is one or more user defined temperature sensors, which
transmission characteristics is defined by the Resistance by 20°C [794] (page 72) and
Resistance in 100°C [795] (page 72) parameters/
PTC thermistor
External temperature sensor is one or more PTC thermistors, which threshold temperature
is defined in the ETP Fault [797] (page 71) parameter. ETP warning occurs after exceeding
the sensor resistance beyond 300 ohm and an ETP fault occurs after exceeding the sensor
resistance beyond 1000 ohm. Drop under 550 ohm causes the fault to disappear.
KTY84
External temperature sensor is one or more KTY 84/130, KTY 84/150, KTY 84/151 sensors.
KTY83/85 2xx External temperature sensor is one or more KTY 83/150, KTY 85/151, KTY 85/152 sensors.
KTY81/82 2xx
External temperature sensor is one or more KTY 81/220, 81/250 or KTY 82/220, 82/250
sensors.
Voltage source
ETP [278]
ETP sensor voltage measurement source signal settings. It is also necessary to
feed the sensor from an analog output, whose function is selected as "ETP
Current".
AIN1
AIN1
Voltage on the thermal sensor is connected to AIN1 (0-10V).
AIN2
Voltage on the thermal sensor is connected to AIN2 (0-10V).
AIN3
Voltage on the thermal sensor is connected to AIN3 (0-10V).
AIN4
Voltage on the thermal sensor is connected to AIN4 (0-10V)
Special
The source of the measurement is the special signal U ETP Signal [95] (page 72).
Sensor count
[793]
Serially connected external temperature sensors count.
1
1 ÷ 10
In case the motor or other device is equipped with multiple identical temperature sensors
(coils, bearings), it is possible to connect them serially, and the count will be defined in this
parameter. Any combination of thermal sensors in the windings and bearings is not allowed!
ETP
Warning
[796]
Temperature in the external sensor temperature scanning point, in which the
inverter generates warning " W13-External temperature (page 29)".
90.0 °C
-500.0
°C
÷
500.0 °C
In case that there are multiple serially connected sensors of an identical type, it is the
average temperature from the multiple measuring points.
ETP Fault [797]
Temperature, in which the inverter generates increased temperature faults in the
external sensor temperature scanning point. Represents the threshold sensor
temperature by 1000ohm when using the ETP=PTC thermistor type. Fault occurs
after exceeding this temperature.
