• A rotation direction change must be made after motor stopped completely.
• When PWM duty is extremely small, two or more switching elements cannot be driven entirely.
In such case, switching elements will generate excess heat and it may cause destruction of the
switching devices. Therefore, extensive heat evaluation is necessary for switching device selection
particularly in consideration of the area of safety operation (ASO).
