Product Description:
The 131F8887 Frequency Converter is a motor controller designed to convert fixed AC mains input into a variable AC waveform output. It enables accurate control of motor speed or torque based on external commands or system feedback.
This 131F8887 frequency converter ensures stable motor operation and includes built in protection functions. Its design supports dynamic motor control, system monitoring and overload safety features suitable for industrial environments. This unit supports an input supply frequency of 50/60 Hz with ± 5 % tolerance. It allows a maximum temporary imbalance of 3.0 % between mains phases. The true power factor reaches ≥ 0.9 under rated load conditions, while the displacement power factor (cos φ) is greater than 0.98 near unity. The system supports a maximum switching frequency of once every two minutes for inputs L1, L2 and L3. It is built for environments classified under EN60664-1 with overvoltage category III and pollution degree 2. The motor output can vary from 0 % to 100 % of supply voltage. The output frequency ranges from 0 - 590 Hz and in flux mode, the limit is 0 - 300 Hz. The switching on output is unlimited. The ramp times can be set from 0.01 to 3600 seconds depending on voltage and power. The torque performance includes a starting torque of up to 150 % for 60 seconds and the same limit for overload torque.
The Danfoss 131F8887 frequency converter functions effectively without derating up to 1000 meters (3281 ft) above sea level and up to 3000 meters (9842 ft) with derating. For communication, the converter uses RS485 serial communication on terminals 68 (P, TX+, RX+) and 69 (N, TX-, RX-) with terminal 61 common to 68 and 69.
Frequently Asked Questions about 131F8887:
Q: How does the VLT 8102 Frequency Converter ensure precise motor response in fast-cycle automation tasks?
A: It uses eight programmable digital inputs with 0–24 V DC logic and an input resistance of approximately 2 kΩ. Each input has a scanning time of 3 ms, enabling quick reaction to control signals.
Q: How does the VLT 8102 Frequency Converter deliver reliable torque performance during motor startup under load?
A: It offers a starting torque of 110% for 1 minute and a breakaway torque of up to 130% for 0.5 seconds. This ensures smooth acceleration even in demanding startup conditions.
Q: What type of output behavior can be expected from the VLT 8102 Frequency Converter in variable speed applications?
A: It delivers 0–100% of the supply voltage and operates over a frequency range from 0 to 120 Hz. This provides flexible speed control for diverse motor types and load profiles.
Q: How does the VLT 8102 Frequency Converter maintain energy efficiency during continuous motor operation?
A: It supports a high true power factor of 0.90 at rated load and maintains a displacement factor above 0.98. This helps reduce reactive power loss and improve overall system efficiency.
Q: How well does the VLT 8102 Frequency Converter protect the system during high fault current events?
A: It withstands a maximum short circuit current of 100 kA, offering robust electrical protection. The recommended switching sequence is limited to once every two minutes to protect internal components.
