Core Functions
Current, speed and position three-loop control ensures stable and high-precision motion performance.
RS01 resolver interface features strong anti-interference, adapting to harsh electromagnetic environments.
Standard 00 hardware version ensures good compatibility and interchangeability.
Internal convection cooling fits conventional cabinet installation conditions.
Complete protection against overvoltage, undervoltage, overcurrent, short circuit, overheating and feedback signal loss.
Supports torque, speed and position control modes to meet diverse load demands.
Modular design facilitates daily maintenance and function expansion.
Application Scenarios
Medium and heavy-load main axes of CNC machine tools using resolver motors
Large textile, printing and packaging machinery operating in complex industrial environments
Gantry systems and heavy-duty automated production and conveying lines
DIAX02 system renovation projects configured with resolver feedback
Automation equipment with limited cabinet space and high operational stability requirements
Usage and Maintenance
Maintain sufficient unobstructed air circulation inside the cabinet for heat dissipation.
Keep ambient temperature below 45 °C to avoid performance decline.
Complete wiring of power, resolver feedback and control circuits before power-on.
Set parameters via IndraWorks according to actual motor and load conditions.
Clean heat dissipation components and air passages every six months, and inspect terminal connections regularly.
Calibrate control loops and resolver signals once a year to maintain long-term stable operation.
