regenerativeIGBTCANopen

Product overview
High-speed networking supporting EtherCAT and CANopen standard protocols. Rich expansion options with optional expansion cards providing different functions. Supports multiple PG cards for enhanced motor control. Equipped with a rectifier braking module enabling a DC common bus for regenerative energy sharing. Independent air-duct design for rapid heat dissipation and improved dust resistance. LCD panel available for fast debugging, parameter storage, upload and download.

Key features

• High-speed operation: maximum output frequency up to 1000 Hz for high-speed rotation and strict speed/torque control.
• High stability and accuracy: extended speed control range with speed fluctuation stabilized to approx. 0.2% to improve mechanical action precision.
• Impact-load adaptability: fast torque response to sudden load changes based on motor current feedback; speed and rotor position adjust output current and torque to suppress vibration.
• Advanced torque vector control: IGBT-integrated modules delivering up to 180% torque at 0.5 Hz startup. Supports 150% overload for 1 minute every 300 s and 180% overload for 3 s.
• Energy efficiency and environmental features: DC reactors improve power factor and reduce harmonics at the supply connection; DC common bus allows multiple converters to share regenerative energy.
• Expanded braking unit power range: standard braking unit power range expanded for more compact and cost-effective control cabinet design.
• PID function: manual adjustment of proportional and integral gains to optimize PID targets and feedback consistency, reducing startup time.
• Positioning function: high-precision positioning via pulse input and encoder feedback to improve accuracy, efficiency and safety.
• Multiple communication methods: built-in isolated RS485 supporting Modbus RTU; supports external expansion for EtherCAT and CANopen.
• Convenient parameter transfer: compatibility mode allows parameters from older models to be written directly to the new model.
• Fast upper-computer debugging: supports Xinje USB-to-serial converter and JC-EV-15 with "Xinje Frequency Converter Debugging Software" for efficient debugging and file management.
• Optional external panels: standard 7-seg LED 5-digit display; optional LCD panel and knob speed-control panel available.
• Lifetime diagnostics and maintenance: internal temperature monitoring and status diagnostics via operation panel and software to detect faults early and reduce downtime.
