Mot temp2 src
Selects the means of temperature measurement for motor
thermal protection 2. When overtemperature is detected the
drive reacts as defined by parameter
Note:
If one FEN-xx module is used, parameter setting must
be either KTY 1st FEN or PTC 1st FEN. The FEN-xx module
can be in either Slot 1 or Slot 2.
Estimated
The temperature is supervised based on the motor thermal
protection model, which uses the motor thermal time constant
(parameter
) and the motor load curve
(parameters
). User tuning is typically needed
only if the ambient temperature differs from the normal
operating temperature specified for the motor.
The motor temperature increases if it operates in the region
above the motor load curve. The motor temperature
decreases if it operates in the region below the motor load
curve (if the motor is overheated).
WARNING!
The model does not protect the motor if
it does not cool properly due to dust and dirt.

KTY 1st FEN
The temperature is supervised using a KTY84 sensor
connected to encoder interface module FEN-xx installed in
drive Slot 1/2. If two encoder interface modules are used,
encoder module connected to Slot 1 is used for the
temperature supervision.
Note:
This selection does not apply to FEN-01.
2
KTY 2nd FEN
The temperature is supervised using a KTY84 sensor
connected to encoder interface module FEN-xx installed in
drive Slot 1/2. If two encoder interface modules are used,
encoder module connected to Slot 2 is used for the
temperature supervision.
Note:
This selection does not apply to FEN-01.
3
PTC JCU
The temperature is supervised using a PTC sensor
connected to DI6.
4
PTC 1st FEN
The temperature is supervised using 1...3 PTC sensors
connected to encoder interface module FEN-xx installed in
drive Slot 1/2. If two encoder interface modules are used,
encoder module connected to Slot 1 is used for the
temperature supervision.
5
PTC 2nd FEN
The temperature is supervised using 1...3 PTC sensors
connected to encoder interface module FEN-xx installed in
drive Slot 1/2. If two encoder interface modules are used,
encoder module connected to Slot 2 is used for the
temperature supervision.
6
Pt100 JCU x1
The temperature is supervised using one Pt100 sensor
connected to analog input AI1 and analog output AO1 on the
JCU Control Unit of the drive.
The analog output feeds constant current through the sensor.
The sensor resistance increases as the motor temperature
rises, as does the voltage over the sensor. The temperature
measurement function reads the voltage through the analog
input and converts it to degrees centigrade.
7
Pt100 JCU x2
The temperature is supervised using two Pt100 sensors
connected to analog input AI1 and analog output AO1 on the
JCU Control Unit of the drive. See
above.
