The values are valid for a pulse frequency set at the factory
2)
At a maximum voltage of 1350 V at the motor terminals
3)
At a maximum voltage of 1500 V at the motor terminals
More information
The permissible length of the motor cable also depends on the quality of the motor cable and
the pulse frequency. The above values apply to high-quality cables, e.g. CY100.
Dimension the motor cable such that the resistance losses are less than 5% of the rated
converter power.
4.1.4 Connecting the converter and converter components
WARNING
Electric shock when the motor terminal box is open
As soon as the converter is connected to the line supply, the motor connections of the
converter may carry dangerous voltages. When the motor is connected to the converter, there
is danger to life through contact with the motor terminals if the motor terminal box is open.
● Close the motor terminal box before connecting the converter to the line supply.
