SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
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 V/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: Displays the motor utilization from the thermal I2t motor model.
Dependency: The motor utilization is only determined for permanent-magnet synchronous motors and if the I2t motor model is
activated.
The motor utilization is formed from the ratio between the I2t motor model temperature (minus 40 Kelvin) and the
reference value p0605 (motor overtemperature, fault threshold) - 40 Kelvin. If p0605 is reduced, r0034 increases
and the motor temperature remains the same.
Refer to: p0611, p0612, p0615
Note: Smoothing time constant = 100 ms
The signal is not suitable as a process quantity and may only be used as a display quantity.
A value of r0034 = -200.0 % indicates an invalid display, for example, because the thermal I2t motor model was not
activated or was incorrectly parameterized.
