The single axis AC/AC converter contains a power module and a control unit for the powerful communication, open and closed-loop control functions.

The SINAMICS S210 servo converter features the following connections and interfaces as standard:

• Fieldbus interface
  • 1 PROFINET interface with two ports (RJ45 sockets) with PROFIdrive V4 profile
• 1 service interface for Ethernet communications with a service PC
• One Cable Connection (OCC)
  • 1 communications connector for communication with the encoder of the SIMOTICS S‑1FK2 motor
  • 1 motor power connector for the power conductors of the SIMOTICS S‑1FK2 motor
  • 1 brake connection for the power conductors of the SIMOTICS S‑1FK2 motor
• 1 connection for the electronic power supply via the 24 V DC supply connector (supply can be looped through connectors for several SINAMICS S210)
• 1 connection for the line voltage and an external braking resistor (optional)
• Digital inputs
  • 1 fail-safe digital input (isolated) for controlling STO and SS1 via terminals
  • 2 high-speed digital inputs for probe or reference marks
  • 1 digital input for monitoring the temperature of an external braking resistor
• 1 slot for a memory card on which the firmware, parameters and licenses can be stored
• 1 display with 3‑digit, 7 segment display for indicating faults and two status LEDs.
• 1 button for acknowledging errors
