SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011
Description: Sets the reference quantity for the technological units. When changing over using changeover parameter 595 to
absolute units, all of the parameters involved refer to the reference quantity.
Dependency: Refer to: p0595
Description: Sets the sensor type for the motor temperature monitoring.
Value: 0: No sensor
1: PTC alarm & timer
2: KTY84
4: Bimetallic NC contact alarm & timer
Dependency: The thermal motor model is only calculated for p0612.1 = 1.
Caution: If, for a selected KTY temperature sensor (p0601 = 2), the motor temperature sensor is not connected but another
encoder, then the temperature adaptation of the motor resistances must be switched out (p0620 = 0). Otherwise, in
controlled-loop operation, torque errors will occur that will mean that the drive will not be able to be stopped.
Note: PTC thermistor (p0601 = 1): Tripping resistance = 1650 Ohm.
Description: Sets the alarm threshold for monitoring the motor temperature.
Dependency: Refer to: p0606
Caution: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation in p0300 should be carefully observed when removing write protection.
Note: The hysteresis for canceling the alarm is 2 Kelvin.
When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (refer to p0300).
