SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011
Description: Sets the winding time constant.
The time constant specifies the warm-up time of the cold stator winding when loaded with the motor standstill cur-
rent up until a temperature rise of 63 % of the continuously permissible winding temperature has been reached.
Dependency: This parameter is only used for synchronous motors (p0300 = 2xx).
Refer to: r0034, p0612, p0615
Refer to: F07011, A07012, A07910
Caution: This parameter is automatically pre-set from the motor database for motors from the motor list (p0301).
When selecting a catalog motor, this parameter cannot be changed (write protection). Information in p0300 should
be carefully observed when removing write protection.
Note: When parameter p0611 is reset to 0, then this switches out the thermal I2t motor model (also refer to p0612).
If no temperature sensor is parameterized, then the ambient temperature for the thermal motor model is referred to
p0625.
Description: Sets the configuration for the thermal motor model.
Dependency: Refer to: r0034, p0611, p0615
Note: Re bit 00:
This bit is only used for permanent-magnet synchronous motors (p0300 = 2xx). It is only possible to switch in ther-
mal I2t monitoring with a time constant greater than zero (p0611 > 0).
Re bit 01:
This bit is used to activate/de-activate the thermal motor model for induction motors.
Description: Sets the fault threshold for monitoring using the thermal I2t motor model.
Dependency: The parameter is only used for permanent-magnet synchronous motors (p0300 = 2xx).
Refer to: r0034, p0611, p0612
Refer to: F07011, A07012
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.
