I2t motor model thermal time constant / I2t mot_mod T

VECTOR_G Can be changed: C2(1, 3), U, T
Data type: FloatingPoint32
P-Group: Motor
Not for motor type: ASM, REL, FEM
Min
0 [s]
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: This parameter is only used for synchronous motors (p0300 = 2xx, 4).
Refer to: r0034, p0612, p0615
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 preassigned 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.

Dependency: For synchronous 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, p0615, p0625, p0626, p0627, p0628
Note: Mot_temp_mod: motor temperature model
Re bit 00:
This bit is used to activate/deactivate the motor temperature model for permanent-magnet synchronous motors.
Re bit 01:
This bit is used to activate/deactivate the motor temperature model for induction motors.
Re bit 02:
This bit is used to activate/deactivate the motor temperature model for 1FK7 motors without encoder.
Motor temperature model 3 cannot be simultaneously activated with another motor temperature model.
