Parameter list
Note: Smoothing time constant: 100 ms
The signal is not suitable as process quantity and may only be used as display quantity.
The torque utilization is available smoothed (r0033) and unsmoothed (r0081).
For M_set total (r0079) > M_max offset (p1532), the following applies:
- demanded torque = M_set total - M_max offset
- actual torque limit = M_max upper effective (r1538) - M_max offset
For M_set total (r0079) <= M_max offset (p1532), the following applies:
- demanded torque = M_max offset - M_set total
- actual torque limit = M_max offset - M_max lower effective (r1539)
For the actual torque limit = 0, the following applies: r0033 = 100 %
For the actual torque limit < 0, the following applies: r0033 = 0 %
r0035 CO: Motor temperature / Motor temperature
VECTOR Can be changed: -
Data type: Floating Point
P-Group: Displays, signals
Min
- [°C]
Description: Displays the actual temperature in the motor.
Note: If neither a temperature sensor nor a PTC thermistor are connected, the temperature of the thermal motor model is
displayed (r0632).
r0036 Power module overload I2t / PM overload I2t
VECTOR Can be changed: -
Data type: Floating Point
P-Group: Displays, signals
Min
- [%]
Description: Displays the power module overload determined using the I2t calculation.
A current reference value is defined for the I2t monitoring of the power module. It represents the current that can be
conducted by the power module without any influence of the switching losses (e.g. the continuously permissible
current of the capacitors, inductances, busbars, etc.).
If the I2t reference current of the power module is not exceeded, then an overload (0 %) is not displayed.
In the other case, the degree of thermal overload is calculated whereby 100% corresponds to the maximum permis-
sible value and results in shutdown (trip) (F30005).
Dependency: Refer to: p0290, p0294
r0037[0...18] Power module temperatures / PM temperatures
VECTOR Can be changed: -
Data type: Floating Point
P-Group: Displays, signals
Min
- [°C]
Description: Displays the temperatures in the power module.
