More Information

Overview Manuals Motor Control Supply Fit Cabinet Design Applications

Features:

  • Compact motor control: The drive varies motor frequency and voltage for adjustable-speed operation.
  • Single- or three-phase input: The documented 200–240 V supply options broaden retrofit use.
  • Constant-torque overload: Short-term 150% capability supports acceleration and transient machine demand.
6SE6420-2UC17-5AA1 is the 0.75 kW, 200–240 V MICROMASTER 420 article for general variable-speed motor control.

The drive becomes application-specific through its motor data, command source, acceleration, protection and I/O parameters.

Its cabinet environment and cooling path remain part of the rating because the IP20 frame is not a stand-alone sealed enclosure.

Apter Power can help confirm Siemens 6SE6420-2UC17-5AA1 supply, motor current, control method and operator-panel scope before quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Variable frequency: Output frequency controls the speed of a compatible AC motor.
  • Motor data: Nameplate voltage, current, frequency and speed establish the control model.
  • Acceleration control: Ramp settings limit mechanical shock and current demand.
  • Protection response: Drive faults identify electrical or thermal conditions before repeated restart.
  • Voltage class: The input must remain within the 200–240 V article range.
  • Phase option: Single- or three-phase supply arrangements are evaluated with current and protection requirements.
  • Grounding: Protective earth and cable shielding are preserved for safe, low-noise operation.
  • Isolation: Stored DC-bus energy is allowed to discharge before terminals are handled.
  • IP20 construction: The drive needs a protective enclosure suited to the site.
  • Heat path: Mounting clearance and cabinet airflow carry losses away from the heatsink.
  • Ambient limit: Enclosure temperature, not room temperature alone, determines thermal margin.
  • Operator panel: BOP or AOP requirements are confirmed separately from the base drive.
  • Conveyors: Adjusts transport speed and provides controlled acceleration.
  • Pumps: Matches flow demand while reducing throttling losses in suitable systems.
  • Fans: Controls airflow with a variable motor-speed command.
  • Legacy machine service: Restores a documented MICROMASTER 420 axis while migration is planned.
Description
6SE6420-2UC17-5AA1 is a compact MICROMASTER 420 inverter for controlling the speed of a suitable three-phase motor from a 200 to 240 V single- or three-phase supply. It provides the power conversion and parameterized control needed for pumps, fans, conveyors and general machine drives.

6SE6420-2UC17-5AA1 is rated at 0.75 kW for constant-torque duty with documented short-term overload capability. Its IP20 frame is intended for a protected cabinet, while the removable operator-panel concept keeps commissioning and daily operation separate from the drive’s power hardware.

Technical notes
Confirm 6SE6420-2UC17-5AA1 supply phase, 200–240 V class, motor current, braking need and control terminals before installation. The IP20 drive requires a suitable enclosure and clear cooling path. Restore the verified parameter set, test rotation uncoupled where possible, and stop if motor data, command source or acceleration behavior differs from the machine record.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can 6SE6420-2UC17-5AA1 be supplied from single-phase mains?
Yes, within the documented 200–240 V input arrangement. Confirm the required line current, upstream protection and motor load rather than sizing only from output kilowatts.
Does 6SE6420-2UC17-5AA1 include an operator panel?
The product description identifies the base drive without AOP or BOP. Confirm whether the quotation must include a compatible panel or whether the installed panel will be reused.
A motor connected to 6SE6420-2UC17-5AA1 runs backward after replacement. What should be corrected?
Stop the drive and verify output phase order and the intended direction command. Do not reverse wiring while the DC bus remains energized.
Why can 6SE6420-2UC17-5AA1 trip in a cabinet that is below the room-temperature limit?
The heatsink sees local enclosure temperature and airflow. Blocked clearance, nearby heat sources or recirculated hot air can remove the drive’s thermal margin.
What should be preserved before replacing 6SE6420-2UC17-5AA1?
Preserve the complete parameter set, motor nameplate, command and speed-reference sources, I/O wiring, ramp times, fault history and operator-panel arrangement.
When should startup of 6SE6420-2UC17-5AA1 be stopped?
Stop for wrong rotation, abnormal motor current, unstable speed, repeated overvoltage or overtemperature faults, or any mismatch between restored parameters and the connected machine.
