HA-220-5 belongs to classic Harmonic Drive HA servo amplifier family, matched with FHA integrated harmonic reduction servo actuators. Main power supply single-phase AC200~240V, DC24V control power for logic, encoder and I/O circuit. It supports incremental encoder and 17-bit absolute encoder signal reading, zero-backlash harmonic actuator closed-loop positioning control.

This servo controller accepts analog ±10V speed/torque command or pulse direction position command. Digital I/O terminals include servo enable, alarm output, home input, positive/negative overtravel limit. Parameter configuration and fault diagnosis are realized by dedicated HD tuning software. Built-in brake transistor for external dynamic brake resistor connection for fast deceleration occasions. It can achieve ultra-high precision positioning and repeatability, suitable for low-speed high-torque joint control.

Comprehensive protection functions include overcurrent, overload, overvoltage, undervoltage, over-temperature, encoder fault, short-circuit and earth fault protection. Protection grade IP20 for cabinet mounting, operating temperature 0~55℃.

HA-220-5 is discontinued legacy Harmonic Drive servo spare part. Many old precision automation machines still adopt HA series servo systems. When the original drive fails, replacing it with identical HA-220-5 can reuse matched FHA harmonic servo actuator, power cable, encoder wiring and original servo parameters. Technicians complete wiring, parameter restore and JOG test, so the precision rotary axis resumes operation and reduces downtime.

Before shipment, every HA-220-5 undergoes comprehensive functional inspection including power-on self-test, I/O signal test, encoder feedback test, command response test, output waveform check and protection function simulation. All products come with 12-month warranty. Our after-sales team provides remote support for installation, wiring guidance, servo parameter tuning and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, HA-220-5 is reliable spare servo controller for legacy Harmonic Drive FHA actuator systems. It restores high-precision closed-loop motion control of zero-backlash harmonic rotary joints, extends service life of precision equipment assets and avoids high-cost whole motion system renovation.
