More Information

Overview Manuals Specifications Thermal Motor Cable Startup

Features:

  • 38 A R3 rating with separate normal and heavy-duty points
  • Thermal planning for reduced-speed and elevated-environment service
  • Motor-cable and serial-network checks that influence reliable operation
ACS550-01-038A-4 is best distinguished by the thermal and motor-system decisions surrounding its 38 A R3 duty.

Long cables, older motor insulation, reduced-speed loading, switching frequency, altitude, and enclosure airflow can change the accessory or derating review without changing the drive type code.

A useful maintenance baseline records cabinet temperature, loaded current, fan and heat-sink condition, serial settings, motor-cable details, and the circumstances surrounding any recurring trip.

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

Drive and cabinet heat management

  • Ambient: Compare the site temperature with the ABB rating and derating instructions.
  • Altitude: Apply the documented current reduction when the installation elevation requires it.
  • Airflow: Keep the R3 heat-sink and fan path clear of recirculation and contamination.
  • Monitoring: Record current, temperature, fan condition, and cabinet air during loaded tests.

Output-circuit engineering

  • Length: Check the installed cable length against ABB guidance and selected switching frequency.
  • Insulation: Confirm motor winding insulation and any required output filtering.
  • Shielding: Terminate the motor-cable shield and PE conductors by the approved method.
  • Routing: Separate the output circuit from signals and communication cabling.

Controlled 18.5 kW startup

  • Motor data: Enter nameplate data and verify limits before coupling normal process load.
  • Rotation: Check direction under controlled conditions with the machine made safe.
  • Controls: Test references, interlocks, local/remote selection, and serial commands.
  • Baseline: Archive parameters and representative operating values for future diagnostics.
Description
Thermal planning becomes more prominent at the ACS550-01-038A-4 duty point. ABB rates this R3 IP21 configuration at 18.5 kW and 38 A for normal use, with a documented heavy-duty point for applications that impose a different overload cycle.

A motor operated by ACS550-01-038A-4 may need special review when it runs slowly for long periods or uses a long cable. Motor self-cooling, insulation, switching effects, cable capacitance, environmental derating, and the possible need for an ABB-approved output solution belong in that assessment.

Reliable service from ACS550-01-038A-4 also depends on clean R3 airflow and a stable serial network. Maintenance should relate fan and heat-sink condition to loaded current and ambient data, while communication troubleshooting should preserve topology, termination, grounding, address, timeout, and command-source evidence.

Technical notes
For ACS550-01-038A-4, check the 38 A motor duty together with ambient temperature, altitude, switching frequency, and R3 cooling because these conditions can require derating. Verify feeder protection, conductor and PE terminations, motor-cable length, braking energy, analog-signal integrity, embedded Modbus timeout behavior, and safe access to the fan and terminals.

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.
At elevated temperature or altitude, how should ACS550-01-038A-4 be derated?
Use the ABB derating instructions when site temperature or elevation exceeds the base rating conditions; also include switching frequency, enclosure airflow, filter condition, and neighboring heat sources.
Which motor-cable conditions justify reviewing an output filter for ACS550-01-038A-4?
Evaluate motor insulation, cable length and capacitance, switching frequency, motor age, bearing-current risk, site EMC requirements, and ABB guidance before selecting any du/dt or other output accessory.
Why can a motor supplied by ACS550-01-038A-4 overheat at reduced speed?
Check load torque, motor self-cooling, minimum speed, current, switching frequency, motor data, mechanical drag, voltage and phase conditions, cable effects, and whether an independently powered fan is required.
When ACS550-01-038A-4 loses serial communication intermittently, what should be inspected?
Inspect network topology, termination, shielding, grounding, unique address, baud and parity, master polling, timeout settings, cable condition, electrical noise, and command-source transitions.
How should cooling maintenance intervals be set for ACS550-01-038A-4?
Set inspection intervals from contamination and duty, then check fan operation, heat-sink cleanliness, filter restriction, cabinet temperature, clearances, recirculation, alarm history, and loaded operating data.
A replacement request for ACS550-01-038A-4 needs which operating records?
Provide the full type code, motor and process duty, supply, R3 mounting and enclosure, cable length, protection, braking, I/O and network use, environmental conditions, quantity, destination, and schedule.
