Features:

  • A 37 kW power stage controls a three-phase motor from a 380–440 V AC supply.
  • USS, Modbus RTU, and BACnet MS/TP share the drive serial communication interface.
  • Integrated digital, relay, analog, and motor-temperature terminals connect the drive to the control system.
Siemens 6SL3220-1YD36-0UB0 converts the line supply into a variable-frequency motor output under V/f or sensorless-vector control.

The terminal set of 6SL3220-1YD36-0UB0 handles commands, status contacts, analog references, feedback, and motor-temperature protection.

Forced-air cooling and the IP20 enclosure of 6SL3220-1YD36-0UB0 require a cabinet layout that maintains the specified airflow and temperature limits.

The Siemens 6SL3220-1YD36-0UB0 SINAMICS G120XA 37 kW USS Variable Frequency Drive may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.

Output and Control-Mode Relationship

  • Power stage: The drive generates the controlled three-phase output for the connected 37 kW motor duty.
  • V/f modes: Linear, square-law, parameterized, FCC, and ECO curves relate output voltage to frequency.
  • Vector mode: Sensorless vector control estimates motor state without an encoder-feedback interface.
  • Commissioning: Motor nameplate data, control mode, ramp times, limits, and rotation checks must be completed as one setup.

Terminal Signal Roles

  • Digital inputs: Six terminals receive configured run, direction, reset, interlock, or other binary commands.
  • Relay outputs: Four dry-contact outputs report assigned status or fault conditions to external circuits.
  • Analog paths: Two differential inputs accept references or measurements, while two outputs transmit configured drive values.
  • Temperature input: The dedicated motor-sensor terminal accepts the documented PTC, KTY, PT1000, or Thermo-Click device.

Serial Network Commissioning

  • Protocol choice: Only the selected USS, Modbus RTU, or BACnet MS/TP stack interprets received telegrams.
  • Station settings: Address, baud rate, parity, stop bits, and timeout must match the network master.
  • Control source: Command and setpoint ownership must be assigned to fieldbus or terminals as required.
  • Process map: The controller data words must correspond to the configured drive control and status mapping.

Cooling and Motor-Connection Boundaries

  • Air path: The integrated fan needs unobstructed cabinet intake and exhaust around the FSD enclosure.
  • Ambient range: Operation at the upper temperature boundary must follow the documented load and installation conditions.
  • Motor cable: Shielded and unshielded cable routes have different maximum documented lengths.
  • Grounding: Protective earth, shield termination, conductor size, and cable routing control electrical safety and interference.
Description
Siemens 6SL3220-1YD36-0UB0 is a SINAMICS G120XA variable frequency drive for three-phase 380–440 V supplies and 37 kW motor duty. Its power stage converts the incoming AC supply into a controlled three-phase output while the embedded control functions regulate motor speed or torque.

The terminal interface of 6SL3220-1YD36-0UB0 separates six digital inputs, four relay outputs, two analog input paths, two analog outputs, and one motor-temperature input. These signals connect commands, interlocks, references, feedback values, and thermal protection to the drive without assigning one terminal to several roles at once.

Serial communication on 6SL3220-1YD36-0UB0 uses the configured USS, Modbus RTU, or BACnet MS/TP protocol. The fieldbus address, baud rate, framing, command source, and setpoint source must agree with the controller because selecting a protocol alone does not map the required control words or process values.

Cooling airflow through 6SL3220-1YD36-0UB0 removes losses from the FSD IP20 enclosure, so cabinet clearance and ambient temperature directly affect the permitted load. Motor-cable length, conductor size, grounding, shielding, and the selected control mode must be evaluated together before the drive and motor are commissioned.
