Procedure of trial run
Power-ON procedure for control circuit of HA-680
Following power supply turning-ON to the driver, the driver identifies the code of the actuator connected
to it automatically. The following operations vary whether the identified code is same as a pre-registered
code or not.
(1) Turn on power to the HA-680 driver. Turn on power to the host.
Make sure there is not an abnormality.
If no indication appears, there may be faulty power connections. Shut off power and inspect
the wiring.
The HA-680 driver identifies the code of the actuator connected to it automatically.
If the actuator code set in the driver and the actuator that is actually connected match:
The green LED (power on) of the HA-680 driver illuminates. As a result of auto identification,
the actuator code matches.
The next operation is turning the servo power ON. Start with the procedure (3) “Turning on
the main circuit power”.
If the actuator code set in the driver and the actuator that is actually connected do not match:
The green LED of the HA-680 driver blinks. As a result of auto identification, the actuator
code does not match.
(2) Shut down the control circuit power supply. Check the adjustment actuator on the nameplate, and
connect a correct actuator. After connection, start again from Step 1.
Turning on main circuit power
(3) Turn on main circuit power, and transmit [ON] signal to [CN2-7 servo-ON: S-ON].
The red LED of the HA-680 driver illuminates. The drive circuit is turned on, and a current
flows through the actuator.
(4) For the position mode, transmit [ON] signal to [CN2 clear: CLEAR] or CN2 deviation clear:
DEV-CLR].
Clear the internal deviation counter to zero.
After that, operation is performed using communication software PSF-520. For details, refer to a
separate document, “PSF-520 User’s Manual.”
