Operating modes of output filters

Output filters can be operated with or without DC link connection. The recommended operation with DC link connection improves the filter effect between the phases and PE. This increases the device utilization.

• Operation with DC link connection
• Nominal filter current ≥ 65 A: Set the minimum clock frequency = 8 kHz.
• Nominal filter current < 65 A: The minimum clock frequency can be set as required.
• Operation without DC link connection
• The maximum clock frequency is 8 kHz.
• The maximum shielded motor cable length is 200 m.
