INOMAX ACS880 Series – Direct Torque Control AC Drive | Replace ABB ACS880, Siemens S120, Vacon NXP
1. Overview
The INOMAX ACS880 series is a high-performance AC drive built on pure Direct Torque Control (DTC) technology. Developed by former ABB, Schneider, and Inovance experts, it delivers the same world-class dynamic performance as top European brands – at a significantly lower cost. With an annual turnover exceeding 200 million RMB (2025) and a defect rate below 1%, INOMAX has become the trusted partner for SANY, XCMG, CRRC, Shougang Group, ZPMC, and many global leaders.
Whether you need a regenerative AFE drive for a dynamometer, a high-torque hoist drive for a mine, or a low-harmonic thruster drive for a ship, the ACS880 provides a true “one-to-one” replacement for ABB ACS880, Siemens Sinamics S120, Vacon NXP, and Yaskawa U1000 – with identical mounting dimensions, same control logic, faster delivery, and 30–50% cost savings.

9. Frequently Asked Questions (FAQ)
Q1: Can I directly replace an ABB ACS880 with INOMAX ACS880 without changing the panel layout?
Yes. The INOMAX ACS880 wall-mounted series shares the exact same drilling template, input/output terminal positions, and overall dimensions as ABB ACS880-01. Cabinet modules fit standard 19″ or 600/800mm deep cabinets. For Vacon NXP, the same mechanical compatibility applies.
Q2: What about communication protocols – does INOMAX support Profinet, EtherCAT, and Profibus‑DP?
Yes. Standard drives come with Modbus RTU and CANopen. Optional plug-in cards add Profinet, EtherCAT, Profibus‑DP, and Ethernet/IP. We also support Vacon NXP’s CANopen object dictionary for seamless replacement.
Q3: Is the built‑in PLC free, or do I need to purchase a license?
All built‑in PLC, logic/math functions, and industry-specific macros (crane anti-sway, winder/unwinder, PCP/ESP, multi-pump) are included free of charge – no license fees.
Q4: Can INOMAX ACS880 be used for permanent magnet motors without an encoder?
Absolutely. DTC provides 200% torque at zero speed even with PM motors, sensorless. For high-precision positioning, encoder feedback is supported.
Q5: What is the typical lead time for INOMAX ACS880 compared to ABB?
Standard wall-mounted units up to 250kW: 2–3 weeks. Cabinet and multi-module drives: 4–6 weeks. ABB and Siemens often have 16–30 week lead times.
Q6: Are INOMAX drives certified for marine applications?
Yes. The ACS880 series is CCS (China Classification Society) certified. We have supplied AFE drives for thrusters, windlasses, and shaft generators on hundreds of vessels including scientific research ships and crane ships.
Q7: How does the price compare to ABB and Vacon?
Typical savings are 30–50% for the same power and feature set. Because we are a direct manufacturer with no brand premium, you get European-level technology at Chinese cost.
Q8: Do you offer liquid‑cooled drives for high power or harsh environments?
Yes. Our L8 series liquid‑cooled drives cover 45kW to 2000kW+ (690V). They are ideal for marine propulsion, high-power test benches, and dusty environments where air cooling is insufficient.
Q9: Can I use INOMAX ACS880 for a dynamometer test bench?
Absolutely. We are a preferred supplier for dynamometer and motor test bench applications. AFE regenerative drives provide <3% THDi and 98% energy feedback. AVL and ZF are our partners.
Q10: What after-sales support do you provide for international customers?
We offer remote commissioning via VPN/TeamViewer, on-site support through local partners in many countries (Southeast Asia, Middle East, Africa, South America), and a 24-month warranty. Spare parts are stocked in Shenzhen for fast shipment.
Q11: Can I get a sample drive for testing before large quantity order?
Yes. We support sample orders and provide engineering support to help you validate the replacement. Contact us with your current drive model and application details.
Q12: How do I migrate parameters from an existing ABB or Vacon drive?
Our free PC tool DriveStudio can import parameter files (.xml, .csv) from ABB and Vacon and convert them into INOMAX format. Most applications can be migrated in under 30 minutes.
Q13: Does INOMAX ACS880 support flying shear and electronic cam for metal cutting lines?
Yes. The ACS880 has built‑in electronic cam, position control, and flying shear functions – no external motion controller needed. Used successfully in slitting lines and cut‑to‑length lines.
Q14: What is the typical lifespan of an INOMAX AC drive?
With high-quality components (Infineon IGBTs, TI DSP, German conformal coating, Japanese fans) and strict quality control, the expected service life is >10 years under normal operating conditions.
Q15: Are there any hidden costs like mandatory software licenses or paid firmware updates?
No. All firmware updates and software tools are free. We believe in transparent pricing.
