Chapter 1 Outlines of HA-680 driver
The HA-680 driver for 24VDC power supply is a dedicated driver that drives the FHA-C mini 24VAC type,
an ultra-thin, hollow shaft structure actuator with a combination of an ultra-thin, precision control
reduction gear Harmonic Drive® and flat AC servo motor, and the RSF supermini series, an ultra-small
AC servo actuator with a combination of an ultra-small Harmonic Drive and ultra-small AC servo motor.
The HA-680 drivers provide many superior functions to allow the FHA-Cmini 24VAC type actuators and
RSF supermini series actuators to excel in performance.
1-1 Main features
Small and compact design
It is about half the size of a postcard, just the size of a card case. Its ultra-light design with a weight of
230 g is useful for small, space-saving devices.
Substantial functions
Position control, speed control, and torque control are provided as standard. It is compact and has
substantial functions at the same time.
Easy function setting
Parameters can be set easily using dedicated communication software PSF-520.
Wide range of operation state display
I/O signals, rotation speed, and deviation can be monitored using dedicated communication software
PSF-520.
Up to eight previous alarms are also indicated as alarm history that is helpful for diagnosis.
The main circuit power supply and the control power supply are separated.
Because the main circuit power supply and the control power supply are separated, safe diagnosis can
be performed in case of failure.
Easy test run adjustment
Adjustment can be performed using dedicated communication software PSF-520.
Electronic gear suitable for mechanical system
The electronic gear function adjusts commands to a feed pitch of a driven mechanism such as gears or
lead screws.
Three types of input signals for position commands
Three types of input signals for the position command are selectable: two-pulse train, single-pulse train,
and two-phase pulse train.
Regenerative circuit provided as standard
It incorporates a regenerative circuit as standard. You can use it in applications with a large moment of
inertia without worrying about regeneration.
