Parameters 287
Defines the warning limit for temperature supervision
function 2. When measured temperature 1 exceeds the limit,
warning
is generated.
The unit is selected by parameter
.
110 °C or
230 °F or
0...4000 ohm
-60…5000 °C or
-76…9032 °F or
0...5000 ohm
Warning limit for temperature monitoring function 2.
Note:
If the measured temperature source selection (
is PTC analog I/O or PTC AI/DI Voltage divider tree, the
motor thermal protection function converts the analog input
signal (
) to PTC resistance value (ohms). Also this limit
is then a resistance value even the parameter name and unit
refer to motor temperature (°C or °F). You cannot change the
unit to ohm by the time being (
).
1 = 1 unit
Specifies the analog input when the setting of
requires measurement through an
analog input.
Not selected
None.
0
AI1 actual value
Analog input AI1 on the control unit.
1
AI2 actual value
Analog input AI2 on the control unit.
2
). -
Defines the ambient temperature of the motor for the motor
thermal protection model. The unit is selected by parameter
.
The motor thermal protection model estimates the motor
temperature on the basis of parameters
…
. The
motor temperature increases if it operates in the region above
the load curve, and decreases if it operates in the region
below the load curve.
WARNING!
The model cannot protect the motor if the
motor does not cool properly because of dust, dirt, etc.
20 °C
-60…100 °C or
-76 … 212 °F
Ambient temperature.
1 = 1°
No.
