Output signal (Nch open drain output) is output by setting [Motor Power] on Port(Nch) in Property setting.
In case that motor port output is used with an external power supply, motor port output is turned ON by
reversed current when motor power for IB turns OFF. Do not turn OFF the motor power for IB while the
external power supply is ON.
The same symptom is seen when a blown fuse error occurs. Then, it is necessary to replace IB.
