* Select a diameter allowable for the current figured out in the control power supply calculation.
* When supplying power by turning ON/OFF 24V DC, leave 0 V connected and supply/cut off
+24 V. Cutting off on the 0V first when cutting off the both ends should make the electric
potential unstable. It may lead to malfunction of components inside the controller.
* The destination for the motor power supply on the driver unit. Maximum allowable current as
the system is 30A.
