FX-Size Chassis Information:
The FX-size chassis (1400×326×356mm) is designed for high-power applications in the 110kW-132kW range. The 132kW model represents the mid-range option within the FX-size family.

Selection Guide:
The 132kW model is the step up from the 110kW model within the same FX-size chassis. For power requirements above 132kW (up to 160kW), transition to the G-size chassis models.

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

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 (compared to 0-650Hz for lower power models) [8†L17-L18].

Q2: What is the ambient temperature range?
A: The operating ambient temperature range is 0°C to +40°C [14†L9]. For environments below 0°C, allow longer warm-up time before applying full load.

Q3: Does this drive include an operator panel?
A: No. This model ships without AOP/BOP. An operator panel is required for parameter changes beyond factory defaults [14†L9].

Q4: What is the typical efficiency of this drive?
A: For 110kW-250kW models, efficiency is 97%-98% [8†L19].

Q5: What protection features are included?
A: Comprehensive protection includes overvoltage, undervoltage, overload, short circuit, ground fault, motor stall prevention, motor lock, motor overtemperature, and drive overtemperature [5†L8-L9].
