Description
PTC sensor or a normally closed thermistor connected relay
to digital input DI6. The motor is overheated when the digital
input is 0.
Normally open thermistor relay connected to digital input DI6.
The motor is overheated when the digital input is 1.
Defines the fault limit for temperature supervision function 1.
When measured temperature 1 exceeds the limit, the drive
trips on fault 4981 External temperature
The unit is selected by parameter
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.
Fault limit for temperature monitoring function 1.
Defines the warning limit for temperature supervision
function 1. When measured temperature 1 exceeds the limit,

The unit is selected by parameter
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.
Warning limit for temperature monitoring function 1.
Specifies the analog input when the setting of
Temperature 1 source requires measurement through an
analog input.
None.
Analog input AI1 on the control unit.
Analog input AI2 on the control unit.
Source selection (see Terms and abbreviations
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.
None. Temperature monitoring function 2 is disabled.
Estimated motor temperature (see parameter
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
