Recommended motor power
The combinations of nominal motor power and inverter model specified in table 3.3.2.1 is based on the use of motors whose
nominal voltages correspond to that of the mains power supply.
If the motors involved have other voltages, select the drive model on the basis of nominal motor current.

Table 3.3.3.1 shows nominal current values for the most typical duty profiles (ambient temperature =
40°C, standard switching frequency).
A similar criterion should be applied to drive operation with additional declassing factors.

3.3.6. Precision
Reference:
Resolution of reference from analog inputs to terminals
0.1 Hz
[full scale function and 1 bit for sign]
Resolution of reference from serial line
0.01 Hz
Open loop speed:
Load related speed loss can be partly compensated for using slip compensation.
Precision nevertheless also depends on the characteristics of the controlled motor.
