180 Parameters
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. 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. 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. 12
31.07 Mot temp2 almLim Defines the alarm limit for the motor thermal protection 2
(when parameter
31.05 Mot temp2 prot is set to either Alarm
or Fault ).
0 … 200 °C Motor overtemperature alarm limit. 1 = 1 °C
31.08 Mot temp2 fltLim Defines the fault limit for the motor thermal protection 2 (when
parameter
31.05 Mot temp2 prot is set to Fault ).
0 … 200 °C Motor overtemperature fault limit. 1 = 1 °C
31.09 Mot ambient temp Defines the ambient temperature for the thermal protection
mode.
-60 … 100 °C Ambient temperature. 1 = 1 °C
31.10 Mot load curve Defines the load curve together with parameters 31.11 Zero
speed load and 31.12 Break point
When the parameter is set to 100%, the maximum load is
equal to the value of parameter
99.06 Mot nom current
(higher loads heat up the motor). The load curve level should
be adjusted if the ambient temperature differs from the
nominal value.
The load curve is used by the motor thermal protection model
when parameter
31.02 Mot temp1 src is set to Estimated .
50 … 150% Maximum load for the motor load curve. 1 = 1%
