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 a 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
Pt100 JCU x1 above.
8
Pt100 JCU x3 The temperature is supervised using three Pt100 sensors
connected to analog input AI1 and analog output AO1 on the
JCU Control Unit of the drive. See
Pt100 JCU x1 above.
9
Pt100 Ext x1 The temperature is supervised using a Pt100 sensor
connected to the first available analog input and analog
output on I/O extensions installed on the drive. See
Pt100
JCU x1 above.
10
Pt100 Ext x2 The temperature is supervised using two Pt100 sensors
connected to the first available analog input and analog
output on I/O extensions installed on the drive. See
Pt100
JCU x1 above.
11
Pt100 Ext x3 The temperature is supervised using three Pt100 sensors
connected to the first available analog input and analog
output on I/O extensions installed on the drive. See
Pt100

31.03 Mot temp1 almLim Defines the alarm limit for motor thermal protection 1 (when
parameter
31.01 Mot temp1 prot is set to either Alarm or
Fault ).
0 … 200 °C Motor overtemperature alarm limit. 1 = 1 °C
31.04 Mot temp1 fltLim Defines the fault limit for the motor thermal protection 1 (when
parameter
31.01 Mot temp1 prot is set to Fault ).
0 … 200 °C Motor overtemperature fault limit. 1 = 1 °C
31.05 Mot temp2 prot Selects how the drive reacts when motor overtemperature is
detected by motor temperature protection 2.
No Motor temperature protection 2 inactive. 0
Alarm The drive generates alarm MOTOR TEMP2 when the
temperature exceeds the alarm level defined by parameter
31.07 Mot temp2 almLim .
1
Fault The drive generates alarm MOTOR TEMP2 or trips on fault
MOTTEMP2 when the temperature exceeds the alarm/fault
level defined by parameter
31.07 Mot temp2 almLim / 31.08
Mot temp2 fltLim (whichever is lower).
