Description:
Displays the smoothed actual value of the active power.
Dependency:
See also: r0082
NOTICE
This smoothed signal is not suitable for diagnostics or evaluation of dynamic operations. In this case, the unsmoothed
value should be used.
Note
Power delivered at the motor shaft.
The active power is available smoothed (r0032 with 100 ms) and unsmoothed (r0082).

Description:
Display and connector output for the motor utilization from motor temperature model 1 (I2t).
For firmware version < 4.7 SP6 or p0612.12 = 0:
- r0034 = (motor model temperature - 40 K) / (p0605 - 40 K) * 100 %
From firmware version 4.7 SP6 and p0612.12 = 1:
- r0034 = (motor model temperature - p0613) / (p0605 - p0613) * 100 %
Dependency:
The thermal motor utilization is only determined when the motor temperature model 1 (I2t) is activated.
The following conditions are a prerequisite for additional information.
- a temperature sensor has not been parameterized (p0600, p0601).
- the current corresponds to the stall current (p0318).
- speed n > 1 [rpm].
For firmware version < 4.7 SP6 or p0612.12 = 0, the following applies:
- the temperature model operates with an ambient temperature of 20 °C.
A motor utilization of 100% is displayed (r0034 = 100 %) when the following conditions are permanently fulfilled:
- the ambient temperature is 40 °C (model 1: p0625 = 40 °C, model 3: p0613 = 40 °C).
From firmware version 4.7 SP6 and p0612.12 = 1, the following applies:
- the ambient temperature can be adapted to the conditions using p0613.

See also: F07011, A07012
NOTICE
After the drive is switched on, the system starts to determine the motor temperature with an assumed model value.
This means that the value for the motor utilization is only valid after a stabilization time.
Note
Smoothing time constant = 100 ms
The signal is not suitable as a process quantity and may only be used as a display quantity.
For r0034 = -200.0 %, the following applies:
The value is invalid (e.g. the motor temperature model is not activated or has been incorrectly parameterized).
