SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Dependency: Refer to: p0601, p0604, p0605, p0614, p0615
Refer to: F07011, A07012, A07910
Note: The I_max reduction is not executed for PTC (p0601 = 1) or bimetallic NC contact (p0601 = 4).
The I_max reduction results in a lower output frequency.
If value = 0:
An alarm is output and I_max is not reduced.
If value = 1:
An alarm is output and a timer is started. A fault is output if the alarm is still active after this timer has expired.
- for KTY84, the following applies: I_max. is reduced
- for PTC, the following is valid: I_max. is not reduced
If value = 2:
An alarm is output and a timer is started. A fault is output if the alarm is still active after this timer has expired.
If value = 12:
Behavior is always the same as for value 2.
For motor temperature monitoring without temperature sensor, when switching off, the model temperature is saved
in a non-volatile fashion. When switching on, the same value (reduced by p0614) is taken into account in the model
calculation. As a consequence, the UL508C specification is fulfilled.
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 (rated motor current, if the motor standstill current is not parameterized) 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 (refer to p0612).
If no temperature sensor is parameterized, then the ambient temperature for the thermal motor model is referred to
p0625.
Description: Setting to activate the motor temperature model.
Dependency: Refer to: r0034, p0604, p0605, p0611, p0615, p0625, p0626, p0627, p0628
Refer to: F07011, A07012, A07910
