More Information

Overview Manuals Specifications 3 kW Duty Cable Route Ramp Setup

Features:

  • 3.0 kW and 7.3 A rating retained in frame R1
  • 24 cubic metres per hour documented cooling airflow
  • 50 percent one-minute overload capability within ABB conditions
ACS355-03E-07A3-4 extends the R1 platform to a 7.3 A continuous duty without changing the narrow cabinet width.

That compactness helps machine builders, but the higher heat and load demand make ventilation, stopping energy, and conductor planning more important than on lower-current R1 units.

Commissioning should demonstrate correct motor rotation, reference ownership, macro behavior, STO response, acceleration, deceleration, loaded current, and a stable thermal condition.

Availability is subject to Apter Power's current inventory and sourcing confirmation.

Load-profile evidence

  • Current margin: Compare measured duty with the documented 7.3 A continuous rating.
  • Overload cycle: Keep repeating torque peaks within ABB time and temperature conditions.
  • Motor cooling: Review prolonged low-speed operation and motor self-ventilation.
  • Stopping: Calculate regenerative energy and resistor heating for repeated cycles.

R1 wiring segregation

  • Supply conductors: Coordinate protection, terminal range, and bend space.
  • Motor cable: Use the approved shield, PE, routing, and length practice.
  • Control signals: Keep analog and serial cables separated from switched power.
  • STO conductors: Route and protect both safety channels according to the validated design.

Motion-profile commissioning

  • Acceleration: Set the ramp from available torque and mechanical limits.
  • Deceleration: Match stop time to braking energy and machine risk.
  • Speed bands: Identify vibration or process ranges that should be avoided.
  • Acceptance: Record current, speed, faults, and process response under representative load.
Description
At the 3 kW duty point, ACS355-03E-07A3-4 remains in ABB's compact R1 frame while raising rated output to 7.3 A. It is an IP20, three-phase 380-480 V machinery drive with the E construction's connected EMC filter and 50 Hz default frequency.

For indexing tables, small mixers, or handling equipment, ACS355-03E-07A3-4 can coordinate sensorless vector control, application macros, programmable references, digital signals, and Safe Torque Off. Its built-in brake chopper supports a stopping design when regenerative energy and resistor duty have been calculated.

Because ACS355-03E-07A3-4 dissipates more heat than the lower R1 ratings, cabinet airflow and cable segregation deserve a fresh review rather than a copied layout. Motor current, starting torque, braking, macro choice, EMC earthing, STO validation, and fuse coordination should close the selection record.

Technical notes
ACS355-03E-07A3-4 remains in frame R1 but requires 24 cubic metres per hour airflow and has a 7.3 A rated output. Recheck cabinet ventilation, 16 A IEC or 20 A UL fuse coordination, motor torque, connected-filter earthing, STO wiring, and braking-resistor duty before transferring settings from a lower-current ACS355.

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 ACS355-03E-07A3-4 replace a lower-current R1 drive without cabinet changes?
The width may match, but ventilation, fuse coordination, conductor size, motor duty, brake-resistor load, parameter limits, and protection still require a new check. Mechanical similarity alone does not prove a safe replacement.
How should the overload cycle of ACS355-03E-07A3-4 be evaluated?
ABB permits a defined 50 percent overload for one minute in ten minutes at the stated conditions. Compare real torque peaks, repetition, ambient temperature, acceleration, and motor heating with that cycle.
Why can ACS355-03E-07A3-4 overheat in a tightly packed enclosure?
Review the 107 W heat loss, 24 cubic metres per hour airflow, top and bottom clearance, air recirculation, neighboring losses, filter contamination, fan condition, ambient temperature, and switching frequency.
What should be checked when ACS355-03E-07A3-4 will not follow its speed reference?
Identify the active control location, reference source, scaling, limits, macro, interlocks, local override, serial timeout, analog wiring, and any constant-speed command that may have priority.
How is a safe deceleration established for ACS355-03E-07A3-4?
Use load inertia, regenerative torque, stop time, repetition rate, chopper limits, resistor resistance and thermal capacity, mechanical brake sequence, and machine risk to define the approved stopping method.
Which commissioning evidence is useful for ACS355-03E-07A3-4?
Retain identifiers, motor data, fuse basis, wiring checks, parameters, macro, STO proof test, rotation, unloaded and loaded current, ramps, stop behavior, faults, thermal readings, and the accepted backup.
