Extended warranty options are available for select products. Contact our sales team for specific warranty details.

Question 7

What is a VFD (Variable Frequency Drive)?

Accepted Answer

A VFD, also known as an inverter or AC drive, is an electronic device that controls the speed and torque of an AC motor by varying the frequency and voltage of the power supply. VFDs are widely used in industrial applications to save energy, improve process control, reduce mechanical stress, and extend equipment life.

Question 8

Which Mitsubishi VFD is right for my application?

Accepted Answer

The right VFD depends on your application requirements. The FR-D700/D800 series is ideal for simple fan and pump applications. The FR-E800 series suits general-purpose applications with advanced features. The FR-A800 offers high performance for demanding applications. The FR-F800 is optimized for fans and pumps with energy-saving features. Use our VFD Finder tool or contact our sales team for a personalized recommendation.

Question 9

What is the price range for Mitsubishi VFDs in Bangladesh?

Accepted Answer

Mitsubishi VFD prices in Bangladesh vary based on the series, power rating, and input voltage. Entry-level FR-D700 drives start from around BDT 15,000, while higher-capacity FR-A800 and FR-F800 models can range significantly higher. Visit our VFD Shop for current pricing on all models, or request a quote for bulk orders.

Question 10

What is the difference between single-phase and 3-phase VFDs?

Accepted Answer

Single-phase VFDs (200V class) accept single-phase AC input and are suitable for smaller motors, typically up to 2.2kW. Three-phase VFDs (200V or 400V class) accept three-phase AC input and are used for larger industrial motors. Three-phase VFDs are more common in factory settings as they offer higher power capacity and better efficiency.

Question 11

How much energy can a VFD save?

Accepted Answer

VFDs can save 20-50% on energy costs depending on the application. The savings are most significant in variable-torque applications like fans, pumps, and blowers where the load varies. Use our Energy Calculator to estimate potential savings for your specific application.

Question 12

Can I use a VFD with my existing motor?

Accepted Answer

In most cases, yes. Mitsubishi VFDs are compatible with standard induction motors. However, the VFD must be properly sized to match your motor’s rated power, voltage, and current. For optimal performance at low speeds or with constant-torque loads, an inverter-rated motor is recommended. Our engineers can help you select the right VFD for your motor.

Question 13

Which Mitsubishi PLC is best for beginners?

Accepted Answer

The Mitsubishi MELSEC FX5U series is an excellent choice for beginners and small-to-medium automation projects. It offers a compact form factor, built-in Ethernet, high-speed counters, and easy programming with GX Works3 software. The FX5U is powerful enough for most applications while being straightforward to learn.

Question 14

What is the difference between FX5U and iQ-R series PLCs?

Accepted Answer

The FX5U is a compact, all-in-one PLC ideal for standalone machines and small systems. The iQ-R series is a modular, rack-based platform designed for large-scale automation with higher I/O counts, faster processing, multi-CPU capability, and advanced networking. Choose FX5U for simplicity and cost-effectiveness, and iQ-R for complex, high-performance systems.

Question 15

What programming software do I need for Mitsubishi PLCs?

Accepted Answer

Mitsubishi PLCs use GX Works3 (for FX5U and iQ-R series) or GX Works2 (for older FX3U/FX3G/Q series). GX Works3 supports ladder, structured text (ST), and function block diagram (FBD) programming. SISL can provide licensed software and training for your team.

Question 16

Does SISL provide PLC programming services?

Accepted Answer

Yes, our FA engineering team offers complete PLC programming and system integration services. This includes logic development, HMI screen design, motion control programming, communication setup, and on-site commissioning. We can develop solutions from scratch or modify existing programs.

Question 17

Can Mitsubishi PLCs communicate with third-party devices?

Accepted Answer

Yes. Mitsubishi PLCs support a wide range of communication protocols including Ethernet/IP, Modbus TCP/RTU, CC-Link, CC-Link IE, PROFIBUS, and serial communication. This makes it easy to integrate with third-party sensors, drives, HMIs, and SCADA systems.

Question 18

What screen sizes are available for Mitsubishi HMIs?

Accepted Answer

The Mitsubishi GOT2000 series is available in screen sizes ranging from 3.8 inches to 15 inches. Popular sizes include 7-inch (GT2107), 10-inch (GT2110), and 12-inch (GT2112) models. Larger 15-inch models are available for applications requiring more display area. All models feature high-resolution TFT displays with touch input.

Question 19

Which GOT2000 model should I choose?

Accepted Answer

For basic monitoring and small machines, the GT27 series (standard type) is cost-effective. For advanced applications requiring data logging, MES connectivity, or video display, the GT27 wide series or GT25 open-frame models are ideal. Consider screen size, required memory, communication ports, and whether you need built-in features like SD card slots or USB ports.

Question 20

Can GOT2000 HMIs connect to non-Mitsubishi PLCs?

Accepted Answer

Yes, GOT2000 HMIs support multi-vendor connectivity. They can communicate with PLCs from Siemens, Allen-Bradley, Omron, Keyence, and many other manufacturers via built-in drivers. This makes GOT2000 a versatile choice even in mixed-vendor automation environments.

Question 21

Is remote access possible with GOT2000 HMIs?

Accepted Answer

Yes, GOT2000 HMIs with Ethernet connectivity support remote monitoring and access. Using Mitsubishi’s GOT Mobile function, you can view HMI screens from a web browser on tablets or smartphones. For more advanced remote access, VPN-based solutions can be configured for secure remote diagnostics and control.

Question 22

What software is used to design HMI screens?

Accepted Answer

Mitsubishi GOT2000 HMIs are programmed using GT Designer3 software. It provides a drag-and-drop interface for creating operator screens, alarms, trends, recipes, and reports. GT Designer3 includes a simulator so you can test your screens before downloading to the HMI hardware.

Question 23

What is the difference between MR-J5 and MR-JE servo amplifiers?

Accepted Answer

The MR-J5 is the latest generation offering the highest performance with a 3.5kHz frequency response, network connectivity (CC-Link IE TSN), and advanced vibration suppression. The MR-JE is a cost-effective option with a 2kHz frequency response, suitable for general positioning applications. Choose MR-J5 for maximum performance and MR-JE for budget-conscious projects.

Question 24

How do I select the right servo motor and amplifier combination?

Accepted Answer

Servo motor selection depends on your required torque, speed, and inertia. Each Mitsubishi servo amplifier model is paired with specific compatible motors. Key factors include continuous torque requirement, peak torque for acceleration, maximum speed, and the inertia ratio between motor and load. Our engineers can help calculate and recommend the optimal combination.

Question 25

Does SISL offer servo commissioning services?

Accepted Answer

Yes, we provide complete servo system commissioning including mechanical installation verification, amplifier parameter setup, auto-tuning, gain adjustment, and performance testing. Our FA engineers have extensive experience with Mitsubishi MELSERVO systems across various applications including CNC machines, packaging equipment, and robotic systems.

Question 26

Can Mitsubishi servos be used for multi-axis synchronized motion?

Accepted Answer

Yes. When combined with Mitsubishi motion controllers (like the iQ-R series with motion modules), MELSERVO amplifiers support sophisticated multi-axis synchronized motion including electronic gearing, electronic cam, linear interpolation, and circular interpolation. CC-Link IE TSN provides high-speed, deterministic communication for precise synchronization.

Question 27

What maintenance do servo systems require?

Accepted Answer

Mitsubishi servo systems are designed for low maintenance. Regular maintenance includes checking cable connections, inspecting for dust buildup, monitoring amplifier temperatures, and checking motor bearings (typically every 20,000-30,000 hours). The amplifier’s built-in diagnostics provide alerts for potential issues before they cause downtime.
