FAQ

• Q: What is the difference between Heavy Duty and Super Heavy Duty current ratings?
  A: Heavy Duty (370A) rating is for variable torque loads (like fans/pumps) with moderate overload. Super Heavy Duty (310A) is for constant torque loads (like conveyors) requiring higher starting torque and frequent overloads; it provides a higher safety margin for demanding conditions.
• Q: What is the benefit of the built-in DC reactor?
  A> The built-in DC reactor reduces harmonic distortion on the input power line, improves input power factor, and helps protect the drive from power line disturbances. It's a valuable feature for high-power drives to ensure network compatibility and reliability.
• Q: Does this drive support network control?
  A> Yes, it comes with a built-in CANopen communication card for integration into CAN-based networks. For other protocols like Modbus TCP/IP or PROFIBUS-DP, you would need to install the corresponding optional communication module.
