Question 7

Is FR-F820-5.5K-1 original Mitsubishi product?

Accepted Answer

Yes, SISL is an authorized Mitsubishi Electric distributor in Bangladesh. All our VFDs including FR-F820-5.5K-1 are 100% original Japan products with proper documentation and warranty.

Question 8

How much energy can I save with FR-F820-5.5K-1?

Accepted Answer

VFDs typically save 20-50% energy in pump and fan applications. The FR-F820-5.5K-1 features optimal excitation control and energy-saving algorithms that automatically reduce power consumption during light load conditions.

Question 9

Why is FR-F800 optimized for fans and pumps?

Accepted Answer

The FR-F800 series features adaptive PID control and energy-optimization algorithms specifically designed for variable torque loads like fans and pumps. It can achieve energy savings of up to 50% compared to fixed-speed operation.

Question 10

What is adaptive PID control in FR-F800?

Accepted Answer

Adaptive PID control in FR-F800 automatically adjusts PID parameters based on system response, providing stable pressure or flow control without manual tuning. This is ideal for water supply and HVAC applications.

Question 11

Is VFD and inverter the same thing?

Accepted Answer

Yes, VFD (Variable Frequency Drive) and inverter are the same thing. Other names include variable speed drive (VSD), AC drive, adjustable frequency drive (AFD), and frequency converter. All refer to devices that control motor speed by varying frequency.

Question 12

Which is better: VFD or soft starter?

Accepted Answer

VFD provides continuous speed control and energy savings, while soft starter only reduces starting current. For applications requiring variable speed or energy efficiency (pumps, fans), VFD is better. For fixed-speed applications with occasional starts, soft starter may be more economical.

Question 13

How to select VFD size for motor?

Accepted Answer

Match VFD rated current to motor full-load current (FLA) with 10-20% safety margin. For 5.5kW motor, FR-F820-5.5K-1 with 25A output is recommended. Always verify motor nameplate and application requirements.
