6.5 Connecting external analog setting devices
Using an external potentiometer (sold separately), external DC voltage, or PWM signal input, the rotation speed or the
torque limiting value can be set.

Note
When a shielded cable is used for connection with the external
potentiometer, connect shields to VL of the pin No.4 from near the
I/O signal connector (CN2).

Using external DC voltage
For external DC voltage, use a DC power supply (0 to 5 VDC) with
reinforced insulation on its primary and secondary sides, and
connect to the pin Nos. 4 and 5 of the CN2.
The input impedance between the VM input and the VL input is
approximately 47 k
Ω
.
The VL input is connected to GND inside the driver.

Be sure to use the voltage of an external control device at 5 VDC or lower.
When connecting an external control device, make sure the polarities are correct. If the polarities are reversed, the
driver may be damaged.

Using PWM signal input
When the operation data is set using the PWM signal input,
connect the PWM signal lines to the pin Nos. 4 and 5 of the CN2.
