Accepted Answer

Yes, SISL is an authorized Mitsubishi Electric distributor in Bangladesh. All our VFDs including FR-D720S-0.4K are 100% original Japan products with proper documentation and warranty.

Question 8

How much energy can I save with FR-D720S-0.4K?

Accepted Answer

VFDs typically save 20-50% energy in pump and fan applications. The FR-D720S-0.4K features optimal excitation control and energy-saving algorithms that automatically reduce power consumption during light load conditions.

Question 9

Does FR-D700 series have Safe Torque Off (STO) function?

Accepted Answer

Yes, the FR-D700 series features built-in Safe Torque Off (STO) function for machine safety. This safety feature allows the motor to coast to a stop when activated, meeting safety standards without requiring external safety relays.

Question 10

What is optimal excitation control in FR-D700?

Accepted Answer

Optimal excitation control is an energy-saving feature in FR-D700 that automatically adjusts motor flux to minimize power consumption during light load conditions. This can reduce energy costs by up to 30% in fan and pump applications.

Question 11

What is the expected service life of FR-D700?

Accepted Answer

The FR-D700 series is designed for a 10-year service life with components rated for long-term industrial use. Regular maintenance and proper installation environment can extend operational life further.

Question 12

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 13

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 14

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 0.4kW motor, FR-D720S-0.4K with 2.5A output is recommended. Always verify motor nameplate and application requirements.
