KTY, MFI2: Error Switch-
Off
Temperature measurement. The frequency inverter is switched off
immediately as soon as the value of Max. Temp. Motor Winding
617 is reached. The error switch-off is displayed by message F0400.
Multifunction input 2 can be reached as input for temperature
measurement with a KTY measuring resistor (KTY84). The input
signal must be analog. Parameter

KTY, MFI2: Err.Switch-
Off 1 min delayed
Temperature measurement. The frequency inverter is switched off
as soon as the value of Max. Temp. Motor Winding 617 is reached.
The error switch-off is displayed by message F0400. The error
switch-off is delayed by one minute. Multifunction input 2 can be
reached as input for temperature measurement with a KTY measur-
ing resistor (KTY84). The input signal must be analog. Parameter
Winding Temperature 226 shows the actual value.

PT1000, MFI2: Warning
only
Temperature measurement. A thermal overload is displayed via the
operator panel and parameter Warnings 269. The warning is dis-
played as soon as the value of
Max. Temp. Motor Winding 617 is
reached. Multifunction input 2 can be reached as input for tempera-
ture measurement with a measuring resistor PT1000. The input
signal must be analog. Parameter

Error Acknowledgment
− Thermal contact or MPTC: An error message can be acknowledged if the sensor does not signal
overtemperature anymore.
− KTY or PT1000: An error message can be acknowledged if the motor temperature has dropped
below the switch-off threshold by 5°C.
Possibilities of error acknowledgement:
− via operator panel or
− via parameter
Error Acknowledgement 103 which is assigned a logic signal or a digital input
Evaluation of the motor temperature is independent of the controller enable.
If motor temperature monitoring with MPTC, KTY or PT1000 is selected via parameter
Operation Mode Motor Temp.
570, multifunction input 2 cannot be used for other
functions. In this case, parameters 560 … 567 of multifunction input 2 don't have any
function.
