8.2 Basic operation

„ Speed setting
„
The setting range is 100 to 4000 r/min.
z Setting by internal potentiometer
„
Use a precision screwdriver to turn the internal potentiometer.
Turn the potentiometer clockwise to increase the speed.
Factory setting: 0 r/min
z Setting by the external potentiometer
„
Connect the supplied external potentiometer to the I/O signal connector (CN5) of the driver.
Use the supplied signal wire [1 m (3.3 ft.)] for this connection.
Ground the shielded wire of the signal wire. Make sure the shielded
wire does not contact other terminals.
When the M0 input is turned ON, the external potentiometer is
enabled. Turn the potentiometer clockwise to increase the speed.

z Setting with external DC voltage
„
Set either 5 or 10 VDC for the external DC voltage. Use
the external voltage selector switch SW2-2 to set which
voltage to be used. 5 VDC is set when the switch is set
to the ON position, and 10 VDC is set when the switch
is set to the OFF position.
Factory setting: 5 VDC (ON)
Note
Change the setting of the external voltage selector switch SW2-2 before turning on the power.
For the external voltage, use a DC power supply (0 to 5 VDC or 0 to 10 VDC) with reinforced insulation on both
the primary side and secondary side, and use the supplied signal wire [1 m (3.3 ft.)] to connect it to the I/O signal
connector (CN5).
Ground the shielded wire of the signal wire. Make sure the
shielded wire does not contact other terminals.
The input impedance between the VM input and VL input is
approx. 15 kΩ when SW2-2 is ON, and approx. 30 kΩ when
OFF. The VL input is connected to IN-COM1 inside the driver.

Note Be sure to set the external DC voltage to either 5 VDC or less, or 10 VDC or less. When
connecting the external DC power supply, make sure the polarities are correct. If the polarities are
reversed, the driver may be damaged.
