• Enclosure Class: MI1-3: IP20, MI4-5: IP21, Cold Plate: IP00.
• Cooling:
  • VACON® 20: Standard air cooling.
  • VACON® 20 Cold Plate: Designed for connection to a cooling element (e.g., heat sink, liquid cooling plate, refrigerants, or metal constructions with high heat energy conducting mass).

Control and Features

• Built-in PLC: Functionality based on IEC61131-3, allowing custom control logic and modification of the parameter list.
• Motor Support: Induction and permanent magnet (PM) motor support.
• Communication:
  • Built-in RS485 interface (Modbus RTU).
  • Optional fieldbus modules for CANOpen, DeviceNet, PROFIBUS DP, Ethernet (Modbus TCP, PROFINET RT), EtherCAT, Ethernet/IP, BACnet MS/TP.
• Parameter Copying: Using the MCA (Micro Communications Adapter) or handheld keypad for VACON® 20 CP, allowing settings to be copied without main power.
• Safe Torque Off (STO): Available on VACON® 20 Cold Plate models according to SIL3.
