HF.. output filters

Observe the following notes if you use an output filter:

• Output filters may only be used in inverter operating modes V/f and VFC^PLUS.
• Calling up the FCB 25 is not permitted when the output filter is connected. Otherwise, the FCB 25 provides incorrect results because of the output filter inductance.
• Output filters may be used up to a maximum inverter output frequency of 250 Hz.
• When selecting the output filter, make sure that it is assigned correctly to the inverter.
• Maintain a ventilation clearance of at least 100 mm below and above the output filter. There is no need for a clearance on the side.
• Limit the length of the cable between the inverter and the output filter to the required length. Maximum permitted length:
• 1 m with unshielded cable
• 10 m with shielded cable
• An unshielded motor supply cable is sufficient when using an output filter.

• Operating modes of output filters
• Voltage drop
• Derating
