3.4 Optional components
Line filter
The inverter is available with and without an integrated line filter. With a line filter, the inverter achieves a higher radio interference class.
Line reactor
The line reactor increases the level of protection for the inverter against overvoltages, harmonics and commutation dips.
In order that the inverter service life is not reduced, a line reactor is required for a relative shortcircuit voltage uk of the line transformer < 1 %.
Sine-wave filter
Sine-wave filters limit the the rate of voltage rise (dv/dt) and the peak voltages at the motor winding. The sine-wave filter increases the maximum permissible length of the motor cables.
Frame size A … frame size F (3 kW … 132 kW): A sine-wave filter is not available.
Output reactor
In order to increase the maximum permissible motor cable length you need one or two output reactors, depending on the inverter.
● Frame size AA … frame size C: An output reactor
● Frame size D … frame size F: Two output reactors connected in series
Braking resistor
The braking resistor allows the inverter to actively brake loads with high moments of inertia.
3.5 Motors and multi-motor drives that can be operated
Siemens motors that can be operated
You can connect standard induction motors to the inverter.
Third-party motors that can be operated
You can operate standard asynchronous motors from other manufacturers with the inverter.
Notice insulation failure due to unsuitable third-party motor: A higher load occurs on the motor insulation in inverter mode than with line operation. Damage to the motor winding may occur as a result.
Multi-motor operation
Multi-motor operation involves simultaneously operating several motors from one inverter. For standard induction motors, multi-motor operation is generally permissible.
