6.4 Sinusoidal filter

CAUTION

If a drive in a Safety Integrated line-up is deactivated via p0105, r9774 is not read correctly because the signals from the deactivated drive are no longer updated.

Remedy: Remove this drive from the group before you deactivate it. See also: Function Manual (FH1), chapter Safety Integrated

6.4Sinusoidal filter

Description

The sinusoidal filter limits the rate of rise of voltage and the capacitive charge/discharge currents that usually occur with inverter operation. They also prevent additional noise caused by the pulse frequency. The service life of the motor is the same as that with direct line operation.

CAUTION

If a sinusoidal filter is connected to the converter, the converter must be activated during commissioning to prevent the filter from being destroyed.

Usage restrictions for sinusoidal filters

The following restrictions must be taken into account when a sinusoidal filter is used:

●The output frequency is limited to a maximum of 150 Hz.

●The modulation type is permanently set to space vector modulation without overmodulation. This reduces the maximum output voltage to approx. 85 % of the rated output voltage.
