Note 1: OC: open collector port, LD: line driver port
Note 2: Function assignment can be performed for the input signals other than servo on (8 to 11 pin) and
the output signals of Outputs 3 and 4 (3, 4 pin).
Note 3: Logic change can be performed for the I/O signals other than Output 5 (Phase-Z OC output)
using “13: Input pin logic setting” and “14: Output pin logic setting” in “Parameter.”
Note 4: “Pin number 18 +24 V” is not the built-in power supply. The HA-680 driver does not incorporate
the internal power supply for pulse input signals. For pulse input signals, an external +24-V
power supply must be supplied.
Do not connect the pins with “-” in the Signal column to the external
device.
If you do, failure may occur because it is connected to the internal circuit.
