Input Signal circuit All input signals of the driver are photocoupler inputs. Use these signals by the internal power supply (+5VDC) or external power supply. When using the external power supply, both sink input logic and source input logic can be used by changing the wiring. Usable external power supply: 24VDC – 15% to +20%, 100mA or more. Output signal circuit The driver outputs signals are photocoupler/collector output. When driving each element using the output signal circuit, give consideration to this ON voltage. ON voltage: 1.5VDC maximum External power supply: 4.5 to 30VDC, 100mA or less (5mA or more for the SPEED-OUT output).

When connecting a relay (inductive load), etc…to detect alarm outputs, use a relay with built-in flywheel diode, or provide a fly-back voltage control measure based on diode, etc…for the inductive load.

Using a external control equipment with a built-in clamp diode If an external control equipment with a built-in clamp diode is used, a leakage path may form and cause the motor to operate even when the external control equipment power is off, as long as the driver power is ON. Since the power capacity of the controller is different from that of the driver,

the motor way operates when the external control equipment and driver powers are tuned on or off simultaneously.

When powering down, turn off the driver power first, followed by the external control equipment power. When powering up, turn on the external equipment power first, followed by the driver power.
