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.”
