13.9.2 Motor temperature monitoring
In order to record and monitor the motor temperature, a PTC thermistor (single sensor
acc
ording to DIN 44081 or triple sensor according to DIN 44082) or thermal contact (normally-
closed contact) can be connected to the terminals T1 and T2. This measure helps to prevent
the motor from being destroyed by overheang.
Precondions
•
The in
verter can only evaluate one PTC thermistor! Do not connect several PTC thermistors
in series or parallel.
•
If several motors are actuated on one inverter, thermal contacts (NC contacts) connected
in series are to be used.
•
To achieve full motor protecon, an addional temperature monitoring funcon with a
separ
ate evaluaon must be installed.
•
By default, a wire jumper is installed between terminals X109/T1 and X109/T2, which must
be removed when the PTC thermistor or thermal contact is connected.
Details
If 1.6 kΩ < R < 4 kΩ at terminals X109/T1 and X109/T2, the monitoring funcon will be acva-
ted; see funconal test below.
•
If the monit
oring funcon is acvated, the response set in 0x2D49:002 will be eected.
•
The seng 0x2D49:002 = 0
deacvates the monitoring funcon.
If a suitable motor temperature sensor is connected to the terminals X109/T1
and X109/T2 and the r
esponse in 0x2D49:002 is set to "Fault [3]", the response
of the motor overload monitoring may be set other than "Fault [3]" in .

Funconal test
Connect a xed resistor to the PTC input:
•
R > 4 kΩ : the monitoring funcon must be acvated.
•
R < 1 kΩ : the monit
oring funcon must not be acvated.
