AutomationDirect: IronHorse ACM Series AC Drives and ACN EtherCAT Communications Module

March 31, 2026
IronHorse ACM series AC drives provide basic V/Hz and sensorless vector control for low-horsepower motors when only single-phase power is available.
These VFDs accept a 120 VAC or 230 VAC single-phase power source and control motors from 1/8 to 3 horsepower. 5 digital inputs, 2 relay outputs, 2 analog inputs, and 1 analog output are standard, along with dynamic braking circuitry. These drives support advanced features normally only found on more expensive drives, such as PID control, 2-motor control, fire mode, momentary power loss restart, and can be password protected to prevent unauthorized changes to the configuration. Programming can be accomplished through the built-in keypad (remote keypad optional) or with the free VFD Suite software. If you are short on space, these drives support zero-stack installation and don’t require spacing between adjacent ACM drives.
Also added is the ACN‑ECAT module that enables any IronHorse ACN series drive to communicate effortlessly over EtherCAT for faster, more integrated motion control.
IronHorse ACM AC drives start at $125.00 (ACM-20P1); the ACN EtherCAT module is priced at $189.00 (ACN-ECAT)
