FX-Size Chassis Information:
The FX-size chassis (1400×326×356mm) is designed for high-power applications in the 110kW-160kW range. The larger enclosure provides superior thermal dissipation and higher current capacity for continuous heavy-duty operation.

Why Choose the 110kW Model?
The 110kW model is the entry point to the FX-size chassis, offering the highest power density in the MM430 series. For applications that have outgrown the 90kW F-size model, this drive provides a natural upgrade path.

Important Notes:
- This product is discontinued. Available ONLY as a spare part
- A BOP or AOP is required for parameter changes beyond factory defaults
- SINAMICS G120 series is the recommended successor for new installations

FAQ:

Q1: What is the output frequency range for this FX-size model?
A: For power ratings 110kW and above, the output frequency range is 0-267Hz (compared to 0-650Hz for lower power models) [8†L17-L18].

Q2: Does this drive include a built-in EMC filter?
A: No. This is the unfiltered version (FB0 suffix). For applications requiring EMC compliance, external filters are available as accessories.

Q3: What is the input current requirement?
A: The input current is approximately 200A at full load [13†L8]. Ensure your supply circuit can handle this current with appropriate branch circuit protection.

Q4: Can this drive be used for multi-pump control?
A: Yes. MM430 includes built-in multi-pump staging logic. Using the relay outputs, it can sequence additional pumps (up to 3 total including the drive-controlled pump).

Q5: What is the typical efficiency of this drive?
A: For 110kW-250kW models, efficiency is 97%-98% [8†L19].
