FR-D700

Summary

Product Identification

• Product Line: FR-D700 Series Inverter
• Manufacturer: Mitsubishi

Features

The FR-D700 series inverters are designed for reliability, ease of use, and enhanced functionality. Key features include:

• Safety Stop Function: Compliant with EU Machinery Directive, providing immediate output shutoff to the motor upon activation of an external Emergency Stop device. Conforms to EN ISO 13849-1 Category 3 / PLd and EN62061 / IEC61508 SIL2 standards.
• High Starting Torque: Achieves 150%/1Hz high starting torque using General-purpose magnetic flux vector control. (Note: 200%/3Hz for 3.7K or less with slip compensation).
• Auto Tuning: Includes Mitsubishi's "non-rotation" auto tuning function for optimal control of various motors.
• Long-Life Design:
  • Cooling fan designed for a 10-year life.
  • Capacitors designed for a 10-year life (rated for 5000 hours at 105°C ambient).
• Life Check Function: Monitors the deterioration of main circuit capacitors, control circuit capacitors, and inrush current limit circuits, providing a self-diagnostic alarm when nearing the end of their lifespan.
• Spring Clamp Terminals: For control circuit terminals, offering easier and more secure wiring. Main circuit terminals are screw terminals.
• Brake Resistor Connection: Built-in brake transistor for 0.4K or higher models. Optional brake resistors can be connected to increase regeneration capability, useful for reducing deceleration time on high-inertia loads.
• Password Function: Allows parameter read/write restriction with a 4-digit password.
• Regeneration Avoidance Function: Automatically increases frequency during regeneration to prevent trips.
• Optimum Excitation Control: Optimizes motor efficiency for energy saving, particularly with variable load torque applications like fans and pumps.
• Power Failure-Time Deceleration-to-Stop Function: Decelerates the motor to a stop upon power failure or undervoltage.
• Dancer Control: Enables tension control using PID control based on dancer roll position signals.
• Traverse Function: Prevents unevenness and deformation in winding applications.
• Compact and Space Saving: Installation size comparable to the FR-S500 series, allowing for side-by-side installation with no clearance.
• Easy Maintenance: Cooling fans are easily replaceable without disconnecting main circuit wires.
• RoHS Directive Compliant: Environmentally friendly design.
• Global Standards Compliance: Complies with UL, cUL, and EC Directives (CE marking). Noise filter options are available for EMC Directive compliance.
• Communication Capabilities: Supports Mitsubishi inverter protocol and Modbus-RTU at speeds up to 38.4kbps.
• PC Software: FR Configurator software available for easy PC-based setup via RS-485 communication, including a conversion function from FR-S500 series parameters.
