G-Size Chassis Information:
The G-size chassis (1533×326×545mm) is the largest chassis in the MM430 series. The 200kW model is the mid-range option within the G-size family (160kW-250kW), offering substantial power for large industrial applications.

Selection Guide:
The 200kW model is the step up from the 160kW model within the same G-size chassis. Choose 200kW when your pump or fan motor is rated 200kW (270 HP) or when the 160kW model is insufficient.

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 designs
- This drive requires careful thermal management due to high power dissipation

FAQ:

Q1: What is the output frequency range for this model?
A: For power ratings 110kW and above, the output frequency range is 0-267Hz [8†L17-L18].

Q2: What is the typical efficiency of this drive?
A: For 110kW-250kW models, efficiency is 97%-98% [8†L19].

Q3: What is the input current requirement?
A: The input current is approximately 370A at full load [7†L19]. 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 based on system demand.

Q5: What cooling requirements does this drive have?
A: The G-size chassis relies on natural air convection cooling. Allow 100mm clearance above and below the drive for proper airflow. Forced cabinet ventilation is typically required due to high power dissipation.
