Features:
- The compact converter combines a 4 kW low-overload power stage with integrated control electronics.
- PROFINET and EtherNet/IP connect the drive to the automation network.
- A dedicated fail-safe input operates the integrated Safe Torque Off function.
Siemens 6SL3210-1KE18-8UF1 controls a three-phase motor from network, digital, or analog commands.
Its onboard inputs and outputs exchange operating states without requiring a separate signal module.
The integrated fan and IP20 enclosure define the cabinet cooling and protection requirements.
The Siemens 6SL3210-1KE18-8UF1 SINAMICS G120C Compact Converter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Command and Feedback Signals
- Digital commands: Six standard digital inputs accept discrete operating signals from the control circuit.
- Analog reference: One differential analog/digital input accepts a 10-bit process value or digital threshold signal.
- Status outputs: One relay and one transistor output return discrete drive conditions to external devices.
- Analog feedback: The non-isolated analog output transmits the assigned operating value to the connected system.
Industrial Ethernet Control
- Network protocols: The integrated interface supports PROFINET and EtherNet/IP communication.
- Command path: Control words and speed references travel from the automation controller to the converter over Ethernet.
- Feedback path: Status words and operating values return from the converter through the same network connection.
- Address setup: Device name, IP parameters, and controller assignment must match the selected industrial Ethernet protocol.
Safe Torque Off Signal Path
- Fail-safe channel: One dedicated input receives the external safety-circuit command.
- Torque response: Safe Torque Off prevents the converter from producing motor torque under the documented conditions.
- Separate function: The safety input is distinct from the six standard digital command inputs.
- Commissioning check: Wiring, parameter assignment, and the complete safety chain must be validated before operation.
Power, Temperature, and Cable Paths
- Motor output: Plug-in screw terminals carry the variable-frequency three-phase output to the motor.
- Thermal sensor: The temperature input accepts PTC, KTY, or Thermo-Click feedback from the motor.
- Braking circuit: The DC-link terminals provide the documented connection path for an external braking resistor.
- Cable limit: Motor cable length and conductor size must remain within the stated terminal and installation limits.
