Harmonic Drive HA-800A-3C-200 AC Servo Driver
A 3 A HA-800A servo driver for 200 V FHA-C actuator systems using the four-wire incremental encoder interface.
Technical Summary
HA-800A-3C-200 is the general-purpose I/O command version of the HA-800 servo-driver platform. Its order code identifies a 3 A output class, the wire-saving incremental-encoder interface and the AC 200 V input class.
Selection should remain tied to the supported FHA-C actuator, encoder wiring and machine command architecture. The final A identifies the general-purpose I/O driver family; the C in the configuration code identifies the encoder interface.

Features
- Supports position, speed and torque operation selected through the documented control setup.
- Uses the reduced-wire incremental feedback interface specified by the C configuration code.
- Provides a general-purpose I/O command path for integration with machine controllers.
- Separates main-circuit and control-circuit supply connections for installation and service planning.
Compatibility
- Match the FHA-C actuator frame, rated current and encoder interface before replacement.
- Confirm the 200 V supply class, command wiring and brake circuit used by the machine.
- Do not treat HA-800B or HA-800C communication versions as direct substitutes for the general-purpose I/O execution.
Replacement
- Save the driver parameters and document motor, encoder, command and safety wiring before removal.
- Compare the full label and supported actuator frame rather than selecting by housing appearance.
- After installation, verify feedback direction, travel limits, brake release, interlocks and controlled low-speed motion.
FAQ
Can HA-800A-3C-200 be used with any FHA-C actuator?
No. The 3 A execution is associated with the supported FHA-17C and FHA-25C frames; confirm the complete actuator nameplate and application load.
Does HA-800A-3C-200 accept a network motion command?
This A-family driver uses general-purpose I/O commands. A change to another HA-800 communication family requires controller and wiring review.
What must be preserved before replacing HA-800A-3C-200?
Keep the parameter set, motor and encoder connections, command I/O assignments, brake wiring and machine safety sequence.
Can a 6 A HA-800 driver automatically replace HA-800A-3C-200?
No. Current class, supported actuator, parameters, protection and commissioning must be checked as an engineered change.
What should accompany an HA-800A-3C-200 enquiry?
Provide clear driver and actuator labels, supply details, parameter backup, connector photographs and the machine command method.
Which commissioning test is most important after fitting HA-800A-3C-200?
Prove feedback direction, brake operation, limits and low-speed axis response before permitting normal machine motion.
