Detachable firmware module enables quick replacement and fast parameter recovery during maintenance.

Compact cooling structure fits cabinet installation with limited space.

Modular design allows flexible function expansion and convenient on-site maintenance.

Comprehensive protection against overvoltage, undervoltage, overcurrent, short circuit, overheating and feedback signal loss.

Supports torque, speed and position control modes for various high-power motion applications.

Application Scenarios

Heavy-duty CNC machine tools and precision machining centers

Large multi-axis automated production lines and handling robots

Metal processing, packaging and large textile machinery

Industrial automation systems using SERCOS bus communication

Usage and Maintenance

Install the drive vertically and ensure adequate ventilation inside the cabinet.

Keep ambient temperature below 45 °C during operation.

Install the firmware module correctly and complete wiring of DC bus, control power, motor cable, feedback cable and SERCOS bus before commissioning. Configure parameters via IndraWorks software.

Clean internal fan and heat sink every 6 months, and inspect terminal connections periodically. Calibrate control loops every 2 years to maintain stable operation.

Transfer the firmware module directly to a new unit for rapid recovery when drive replacement is needed.
