The ABB ACS580-01-039A-4 is an 18.5 kW (25 HP) general-purpose wall-mounted variable frequency drive with 38A rated output (36.1A light duty, 31.6A heavy duty) and 56.9A peak current. Operating from 380–480V three-phase input, it supports V/f, sensorless vector, and optional closed-loop flux vector control with external encoder feedback up to 500 Hz. Housed in an IP21 R3 frame measuring 203 × 229 × 490 mm and weighing 14.9 kg, it features an integrated gland box and supports external braking resistors (10–22 ohm, up to 25 kW). The 24V control unit auxiliary input maintains control power when mains is disconnected. With 6 DI, 2 AI, 2 AO, 3 RO, built-in RS485 Modbus RTU, optional multi-protocol fieldbus, Assistant Control Panel, SIL3 dual-channel STO, and IE2 efficiency, it is ideal for demanding HVAC, pump, compressor, conveyor, and process control applications.
Q: Does the ACS580-01-039A-4 support closed-loop vector control?
A: Yes, with an optional encoder feedback card installed, the drive supports full closed-loop flux vector control for precise speed and torque regulation.
Q: What is the 24V auxiliary input used for?
A: The 24V DC/AC auxiliary input powers the control unit independently of the main supply, allowing parameter access, diagnostics, and fieldbus communication even when mains power is disconnected.
Q: What external braking resistor is recommended?
A: A 22-ohm external braking resistor is recommended, with a 10-ohm minimum and up to 25 kW braking power.
Q: What are the dimensions and weight?
A: The drive measures 203 × 229 × 490 mm (W×D×H) and weighs 14.9 kg, with an integrated gland box for cable entry.
