h. Connecting the I/O signals on the 10 and 25L Driver

Connect the I/O signals to CN4 on the driver. Insert each wire into the connector as shown on the picture. Recommended lead wire: AWG24 to 18 (0.2 to 0.75mm²) Recommended length of bear wire 10mm. CN4 pin assignment

* The signal in brackets [ ] is a function that is assigned at the time of shipment. The assigned functions can be changed by setting parameters. All input signals of the driver are photocoupler inputs. Use these signals by the internal power supply (+5 VDC) 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, 100mA or above.

The driver outputs signals are photocoupler/open-collector output. The ON voltage of the output circuit is max 1.5V. When driving each element using the output signal circuit, give consideration to this ON voltage. External power supply: 4.5 to 30VDC, 100mA or

below (for the SPEED-OUT output, supply a minimum of 5mA current).

 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.
