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).

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.
