Frequently asked questions
Which control method and pulse frequency does the filter require?
Use V/f or FCC control only, with a pulse frequency of 4 kHz. Automatic pulse frequency reduction must be disabled. Operation at 2 kHz causes the filter to overheat. Operate with a connected load and observe the power-dependent output-frequency limits listed in the table.
Is the same product family enough to identify a replacement?
The complete order number is essential. If the type changes, compare the electrical and mechanical design, connections and requirements of the original application.
What information is needed to check connections and accessories?
Send a nameplate photo, the designations of related modules and connectors and, where needed, a wiring diagram. We will check the specific version for your application.
Can you assess a faulty part?
Yes. Send the complete order number and a description of the fault. We will check the diagnostic and professional repair options for your specific unit.
