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.
For bit 12 (only effective if a temperature sensor has not been parameterized):
This bit is used to set the ambient temperature for 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 with an ambient temperature of 20 °C.
The following applies from firmware version 4.7 SP6 (bits 0 and 12):
- the ambient temperature can be adapted to the conditions using p0613.
Description: Sets the ambient temperature for motor temperature model 1 or 3.
- temperature model 1 (I2t, p0612.0 = 1):
For firmware version < 4.7 SP6 or p0612.12 = 0, the following applies:
The parameter is not relevant.
From firmware version 4.7 SP6 and p0612.12 = 1, the following applies:
The parameter defines the current ambient temperature.
- temperature model 3 (p0612.2 = 1):
The parameter defines the current ambient temperature.
Dependency: Refer to: p0612
Refer to: F07011, A07012
Description: Sets the reduction factor for the overtemperature of the thermal adaptation of the stator/rotor resistance.
