2.2 List of parameters
Description: Displays the smoothed actual value of the active power.
Dependency: Refer to: 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: Displays the smoothed torque utilization as a percentage.
The torque utilization is obtained from the required smoothed torque in reference to the torque limit, scaled using
p2196.
Dependency: This parameter is only available for vector control. For U/f control r0033 = 0 %.
Note: Smoothing time constant = 100 ms
The signal is not suitable as a process quantity and may only be used as a display quantity.
The torque utilization is available smoothed (r0033) and unsmoothed (r0081).
For M_set total (r0079) > 0, the following applies:
- Required torque = M_set total
- Actual torque limit = M_max upper effective (r1538)
For M_set total (r0079) <= 0, the following applies:
- Required torque = - M_set total
- Actual torque limit = - 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 %
Description: Display and connector output for the motor utilization from motor temperature model 1 (I2t) or 3.
For motor temperature model 1 (I2t) (p0612.0 = 1), the following applies:
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 %
For motor temperature model 3 (p0612.2 = 1), the following applies:
- r0034 = (motor model temperature - p5397) / (p5398 - p5397) * 100 %
