Features
The RSF supermini series are ultra-small AC servo actuators combining ultra-precision control deceleration device Harmonic Drive® that provides precision rotation operation at a high torque with ultra-small AC servo motor developed to make use of the performance of the decelerator.
Actuators with an electromagnetic brake are also included in the lineup. They can meet fail-safe requirements of equipment to prevent accidents upon power supply failure. The dedicated servo driver HA-680 is an AC servo driver for 24VDC power supply. The small and multi-functional HA-680 driver is equipped with position control, speed control, and torque control as standard to control operation of the RSF supermini series correctly and precisely.

• Relay cables
There are relay cables that connect the RSF supermini series actuator and driver. There is relay cable that connect the driver and PC.
Application cables Model
For motors EWA-M**-JST04-TN2
For encoders EWA-E**-M09-3M14
For brakes EWA-B**-JST03-TMC
For EIA-232 HDM-RS232C(the cable length 1.5m)
*(** indicates the cable length 3m, 5m, or 10m.)

• Connectors
There are 2 types of connectors for the driver for different set types:
•Connector model: CNK-HA68-S1
For CN1, CN2, actuator line connection, power supply connection .... 4 types(CN1, CN2, TB1, TB2)
•Connector model: CNK-HA68-S2
For CN2, power supply connection .... 2 types(CN2, TB2)
The relay cable for the encoder is necessary for the connection with the driver.
*The relay cable for brake is necessary for the actuator with the brake.
*When the actuator with the brake is used, the relay cable for the brake is necessary.

• Dedicated communication software PSF-520 (free)
This software allows you to set and/or change parameters to the HA-680 driver from your PC.
Dedicated communication software PSF-520 can be downloaded from our website at http://www.hds.co.jp/.
To change the servo parameters of the driver, connect "CN3" of the HA-680 driver and the PC with dedicated communication software PSF-520 installed with the EIA-232C cross cable (dedicated cable HDM-RS232C: Cable length 1.5 m).

Note 1: The table shows typical output values of actuators.
Note 2: the values in the table above are obtained when it is combined with the combined driver (HA-680-4B-24).
Note 3: The moment of inertia is the total value of the motor shaft and Harmonic Drive moment of inertia values converted to the output side.
Note 4: The encoder resolution is (motor shaft encoder resolution when multiplied by 4) x (gear ratio).
