Controlled Outgoing Circuit For Auxiliary Equipment 400 V 3 Ac (Option N30); Sine-Wave Filter (Option Y15); Table 3-2 Max. Permissible Cable Lengths - Siemens 6SL3845-2NN41-8AD2 Operating Instructions Manual

The capacitors are installed in three additional cabinets (each 3x2 mF). Together with the
capacitance of the base unit (12 mF), this produces a DC-link capacitance of 30 mF.

Controlled outgoing circuit for auxiliary equipment 400 V 3 AC (option N30)

This option includes a controlled outgoing feeder for external auxiliaries (3 AC 400 V, max.
4 KW). The controlled outgoing feeder is protected by a circuit breaker. The circuit breaker
setting range is cos phi = 0.8 (7 A up to 10 A).
The option can be used to operate external fans on motors and pumps and oil supply units. The
"ON" command at the drive closes the contactor. The "OFF" command opens the contactor.
Externally provide the necessary drive power supply. The terminal assignment is provided in
the circuit diagram of the drive.
3.6.26

Sine-wave filter (option Y15)

This option allows line motors or motors with insulation systems that are not compatible with
drives to be operated with speed control. The sine-wave filter supplies the motors with virtually
sinusoidal motor currents and voltages, which means that line motors can be used. Standard
cables (without EMC shielding) can also be used between the sine-wave filter and the motor.
When sine-wave filters are used, the voltage harmonic distortion at an output frequency of 50
Hz is less than 5%. When the sine-wave filter is used, refer to the performance data (see the
technical specifications). Only work machines with square load characteristic curve (centrifugal
pumps and water turbines) can be operated. Field-weakening operation is not permitted.
Possible rated output frequencies are limited to a range of 30 Hz to max. 66 Hz. The frequency
setting range is 1:10.
