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.
For bit 02:
This bit is used to activate/de-activate the motor temperature model for 1FK7 Basic and 1FL5 motors.
Motor temperature model 3 cannot be simultaneously activated with another motor temperature model.
For bit 08:
This bit is used to extend the motor temperature model 1 (I2t).
The following applies for firmware version < 4.7 SP6 (only bit 0):
- this bit has no function. Temperature model 1 operates in the standard mode.
Overtemperature at rated load: p0605 - 40 °C
Alarm threshold: p0605
Fault threshold: p0615
The following applies from firmware version 4.7 SP6 (bits 0 and 8):
- temperature model 1 operates in the extended mode.
Overtemperature at rated load: p0627
Alarm threshold: p5390
Fault threshold: p5391
For bit 09:
This bit is used to extend the motor temperature model 2.
For firmware version < 4.7 following applies (only bit 1):
- this bit has no function. Temperature model 2 operates in the standard mode.
From firmware version 4.7 the following applies (bits 1 and 9):
- this bit should be set. Temperature model 2 then operates in the extended mode and the result of the model is more
precise.
