STD output as positive, when the feedback signal is greater than STD setting, the
inverter output frequency is required to drop in order to balance STD. Such as winding
tension STD control.
STD output as negative, when the feedback signal is greater than STD setting, the
inverter output frequency is required to rise in order to balance STD. Such as
unwinding tension STD control.
