Parameters 201
Therm(0) PTC sensor or a normally closed thermistor connected relay
to digital input DI6. The motor is overheated when the digital
input is 0.
21
Therm(1) Normally open thermistor relay connected to digital input DI6.
The motor is overheated when the digital input is 1.

35.12 Temperature 1 fault
limit
Defines the fault limit for temperature supervision function 1.
When measured temperature 1 exceeds the limit, the drive
trips on fault 4981 External temperature 1.
The unit is selected by parameter 96.16 Unit selection.
Note: With a PTC sensor, changing the value of this
parameter has no effect on fault generation. When PTC is
over the triggering threshold of the CMOD-02 (see the
Hardware manual), the drive trips on the fault and when PTC
has decreased below recovery threshold of the CMOD-02
(see the Hardware manual), the fault is reset.

35.13 Temperature 1
warning limit
Defines the warning limit for temperature supervision
function 1. When measured temperature 1 exceeds the limit,
warning A491 External temperature 1 is generated.
The unit is selected by parameter 96.16 Unit selection.
Note: With a PTC sensor, changing the value of this
parameter has no effect on warning generation. When PTC is
over the triggering threshold of the CMOD-02 (see the
Hardware manual), the drive trips on the fault and when PTC
has decreased below recovery threshold of the CMOD-02
(see the Hardware manual), the fault is reset.

35.14 Temperature 1 AI
source
Specifies the analog input when the setting of 35.11
Temperature 1 source requires measurement through an
analog input.
Not selected
Not selected None. 0
AI1 actual value Analog input AI1 on the control unit. 1
AI2 actual value Analog input AI2 on the control unit. 2
Other Source selection (see Terms and abbreviations on page 100). -
35.21 Temperature 2
source
Selects the source from which measured temperature 2 is
read.
Usually this source is from a sensor connected to the motor
controlled by the drive, but it could be used to measure and
monitor a temperature from other parts of the process as long
as a suitable sensor is used as per the selection list.
Disabled
Disabled None. Temperature monitoring function 2 is disabled. 0
Estimated
temperature
Estimated motor temperature (see parameter 35.01 Motor
estimated temperature).
The temperature is estimated from an internal drive
calculation. It is important to set up the ambient temperature
of the motor in 35.50
Motor ambient temperature.
