INOMAX ACS580 AC Drive – Direct Replacement for ABB ACS580, Siemens G120, Danfoss VLT, Vacon 100
1. Overview
The INOMAX ACS580 is a general purpose AC drive engineered for variable and constant torque applications such as pumps, fans, conveyors, compressors, mixers, extruders, and HVAC systems. It is a direct functional and mechanical replacement for ABB ACS580, Siemens Sinamics G120, Danfoss VLT HVAC/FC Series, Vacon 100, Schneider ATV600, and Yaskawa GA800.
Developed by a core team with decades of experience at ABB, Schneider, and Inovance, INOMAX delivers the same proven control architecture – Direct Torque Control (DTC) – at 30–50% lower cost than European and Japanese brands. With over 200,000 units deployed globally, a defect rate <1%, and 100% full‑load motor testing, the ACS580 is trusted by system integrators, EPCs, and distributors in mining, water, cement, steel, marine, and oil & gas.
Key differentiators: built‑in PLC (free), multi-pump control, sleep/wake, anti‑condensation heater control, energy optimizer, and full compatibility with ABB Drives PC tool migration.

9. Frequently Asked Questions (FAQ)
Q1: Can I use the INOMAX ACS580 as a direct replacement for an ABB ACS580 without modifying my panel?
Yes. The INOMAX ACS580 shares identical mounting dimensions, power terminal locations, and control I/O layout with ABB ACS580-01. Our free DriveStudio software can convert ABB parameter files (.xml, .bmp) into INOMAX format, typically completing a retrofit in under 2 hours.
Q2: Does the INOMAX ACS580 support built‑in multi‑pump control for pressure boosting systems?
Absolutely. Up to 8 pumps can be controlled directly – alternating lead pump, staging/destaging based on PID error, sleep/wake, and dry run protection. No external PLC required.
Q3: What communication protocols are available for connecting to a Siemens PLC?
Standard ACS580 includes Modbus RTU and CANopen. Optional plug‑in cards provide Profinet, EtherCAT, Profibus‑DP, Ethernet/IP, and BACnet. We have successfully integrated with Siemens S7‑1200/1500, Rockwell CompactLogix, and Schneider M340.
Q4: How does the price of INOMAX ACS580 compare to Danfoss VLT or Yaskawa GA800?
You will typically save 30‑50% compared to Danfoss, Yaskawa, or Siemens, and 35‑50% compared to ABB. For example, a 37kW INOMAX ACS580 is priced at approximately 40% of ABB’s list price – same performance, more built‑in features.
Q5: What is the typical lead time for a 55kW general purpose AC drive?
Standard wall‑mounted units up to 250kW: 2‑3 weeks for production + shipping. Express service (1‑2 weeks) available for sample or urgent orders. Compare with ABB 16‑30 weeks and Siemens 20‑35 weeks.
Q6: Is the built‑in PLC free, or do I need to purchase a license key?
The PLC is fully functional and free – no license, no activation, no recurring fees. It supports ladder logic, function blocks, and structured text for simple sequencing, logic, math, and interlocking.
Q7: Can the INOMAX ACS580 drive a permanent magnet motor (PM motor) in sensorless mode?
Yes. DTC provides excellent PM motor control without encoder, including 150% starting torque. For high‑precision applications, optional encoder feedback (HTL, TTL, resolver) is supported.
Q8: Does INOMAX ACS580 have a built‑in energy log and kWh counter?
Yes. The drive displays real‑time power (kW), energy (kWh), and CO₂ savings. You can reset the counter monthly for energy reporting.
Q9: What is the difference between INOMAX ACS580 and INOMAX ACS880?
ACS580 is our general purpose drive optimized for pumps, fans, conveyors – with built‑in PID, multi‑pump, and energy optimizer. ACS880 is our high‑performance DTC drive with <5ms torque response, AFE regenerative option, and advanced applications (crane, winder, dyno). For 80% of standard industrial applications, ACS580 is the most cost‑effective choice.
Q10: Do you offer a 690V version of ACS580 for mining and marine?
Yes. We offer 690V ACS580 drives from 45kW to 500kW (cabinet version). Please contact us with your voltage and power requirements.
Q11: Can I get a sample drive for evaluation before placing a large order?
Absolutely. We support sample orders and provide full engineering support during evaluation. Many distributors started with 2‑5 units for testing before annual contracts of 500+ units.
Q12: Does INOMAX ACS580 support flying start to catch a spinning fan or pump?
Yes. The flying start function scans the motor speed and seamlessly locks onto it without tripping – essential for fan retrofits or pump systems with backflow.
Q13: Are INOMAX drives compliant with marine classification societies?
CCS (China Classification Society) certification is available for ACS580 series. We are also in progress for ABS and BV. Thousands of drives are installed on cargo vessels, dredgers, and offshore platforms.
Q14: What is the typical lifespan of an INOMAX AC drive?
With high‑grade components and 100% full‑load testing, the expected service life exceeds 10 years under normal operating conditions. Our first generation drives (2014) are still running in the field.
Q15: Do I get technical support if I’m a distributor in Africa or South America?
Yes. We provide remote support via TeamViewer, WhatsApp, and WeChat. For major projects, we can dispatch engineers or train your local team. Spare parts are shipped from Shenzhen within 24‑48 hours.
Q16: Where can I download the user manual and PC software for the ACS580 general purpose drive?
All documentation and DriveStudio software (parameter backup, cloning, migration from ABB/Siemens/Danfoss) are available for free on our website after a quick registration. No paid subscription.
Q17: Can I use the INOMAX ACS580 for a solar pump inverter application?
For grid‑connected pump systems, yes. For off‑grid solar direct drive (DC input), please see our dedicated solar pump inverter series (SPI series) which includes MPPT and dry run protection specifically for solar irrigation.
