Product Description:
The 131F6658 Frequency Converter from Danfoss provides dependable operation for industrial motor control systems. It is compatible with high short circuit capacity circuits and supports up to 65 kA SCCR at 480 - 600 V.
The 131F6658 frequency converter is designed with three phase supply terminals L1, L2 and L3. It accepts a wide input voltage range from 380 – 480 V or 500 V ± 10 % with 50 - 60 Hz ± 5 % supply frequency. The product supports high efficiency operation in demanding environments. The frequency converter accommodates a maximum imbalance of 3 % between mains phases based on the rated supply voltage. It features a true power factor of ≥ 0.9 under rated load and a displacement power factor close to unity (> 0.98) that supports energy efficiency. The switching frequency on the input supply is limited to one time per two minutes. The unit complies with EN 60664-1 and offers overvoltage category III and pollution degree 2 classification. The output frequency ranges from 0 – 590 Hz without a sine wave filter. With a sine wave filter and no derating, the unit can operate up to 60 Hz and with derating up to 100 Hz. In flux mode, the frequency extends to 300 Hz that provides broad control for specialized applications.
The 131F6658 frequency converter allows unlimited switching on output and programmable ramp times between 0.01 – 3600 seconds for precise motor acceleration or deceleration. The converter is capable of delivering up to 150 % starting torque for 60 seconds every 10 minutes when operating under constant torque conditions. For variable torque conditions, it can deliver up to 110 % for 0.5 seconds every 10 minutes. These capabilities ensure it can manage heavy duty startups and load variations without failure.
Frequently Asked Questions about 131F6658:
Q: How does the 131F6658 frequency converter handle phase imbalance in industrial power systems?
A: It tolerates up to 3% imbalance between the three mains phases based on the rated input. This ensures reliable motor operation even with slight voltage asymmetry in supply networks.
Q: What control flexibility does the 131F6658 frequency converter offer for specialized motor-driven applications?
A: It supports an output frequency up to 590 Hz without a sine wave filter and up to 300 Hz in flux mode. This allows broader speed control in high-speed or process-intensive systems.
Q: How does the 131F6658 frequency converter manage torque-heavy startups in constant load environments?
A: It delivers 150% starting torque for 60 seconds in every 10-minute duty cycle. This capability ensures dependable starts for motors driving high-inertia mechanical loads.
Q: What protection and installation conditions should be considered for the 131F6658 frequency converter in harsh industrial settings?
A: It conforms to EN 60664-1, rated for overvoltage category III and pollution degree 2. These ratings ensure robust installation in control cabinets with industrial-level transients and moderate contamination.
Q: How does the 131F6658 frequency converter enable precise motor control during speed transitions?
A: It offers programmable ramp times from 0.01 to 3600 seconds, allowing tailored acceleration and deceleration profiles. This ensures smooth transitions even in high-precision applications or sensitive loads.
