2.2 List of parameters
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 current
(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: The parameter is only used for synchronous motors (p0300 = 2xx, 4) and synchronous reluctance motors (p0300 =
6xx).
Refer to: r0034, p0612, p0615
Refer to: F07011, A07012, A07910
Notice: 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.
When exiting commissioning, p0612 is checked, and where relevant, is pre-assigned to a value that matches the
motor power, if a temperature sensor was not parameterized (see p0601).
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: For synchronous motors and synchronous reluctance motors, when exiting commissioning, temperature model 1 is
automatically activated if a time constant has been entered in p0611.
Refer to: r0034, p0604, p0605, p0606, p0611, p0613, p0615, p0625, p0626, p0627, p0628, r0630, r0631, r0632,
r0633, p5350, r5389, p5390, p5391
Refer to: F07011, A07012, A07014, A07910
Notice: For bit 00:
This bit is only automatically activated for permanent-magnet 1FT7 synchronous motors and synchronous reluctance
motors. For other permanent-magnet synchronous motors, the user himself must activate motor temperature model
1 (I2t).
It is only possible to activate this motor temperature model (I2t) for a time constant greater than zero (p0611 > 0).
Note: Mot_temp_mod: motor temperature model
For bit 00:
This bit is used to activate/de-activate the motor temperature model for permanent-magnet synchronous motors and
synchronous reluctance motors.
For bit 01 (see also bit 9):
This bit is used to activate/de-activate the motor temperature model for induction motors.
