• MDS-B-SVJ2 (200V) – Designed for CNC machinery.
• MDS-B-V1-20 (200V) – Ideal for smaller motors.
• MDS-B-VR (200V) – Used in medium-duty regenerative applications.

2. Power Capacity & Speed: Superior Performance with MDS-C1

The MDS-C1 series delivers significantly higher power and speed than the MDS-B series, making it ideal for high-performance CNC machines and automation systems.

• MDS-C1-SPH reaches 3000 RPM and supports up to 11 kW, perfect for high-speed CNC applications.
• MDS-C1-SVJ offers 7.5 kW power output with 400V support, ensuring precise motion control at high speeds.
• MDS-C1-V1-45 (200V) provides 4.5 kW, balancing moderate power capacity with efficiency.
• MDS-B-SVJ2 has a lower power output of 3.5 kW and 2000 RPM speed, making it more suitable for conventional CNC applications.
• MDS-B-V1-20 offers a maximum of 2kW at 1500 RPM, best for compact automation systems.

3. Communication Protocols & Connectivity: Advanced Integration

The MDS-C1 series supports modern communication technologies, making it better suited for complex automation networks.

• MDS-C1-SVJ features CC-Link IE Field for synchronized control.
• MDS-C1-SPH supports EtherCAT for real-time data exchange in CNC environments.
• MDS-C1-V1-45 includes Modbus TCP/IP for flexible connectivity.

4. Safety Features: Ensuring Secure Operations

The MDS-C1 series provides advanced safety features such as:

• Safe Torque Off (STO) – Prevents unintended motor movement.
• Safe Stop 1 (SS1) – Ensures a controlled stop to prevent damage.
• Emergency Stop & Overload Protection – Found in MDS-C1-V1-45.

5. Diagnostics & Predictive Maintenance: Maximizing Uptime

The MDS-C1 series features real-time diagnostics and predictive maintenance:

• MDS-C1-SPH uses CC-Link IE for fault diagnostics.
