DC Controls

	One Way One-way DC controls are designed to operate permanent magnet or wound field motors. If the motor's rotation needs to be changed, the armature leads need to be reversed. Some NEMA 1 and NEMA 4X controls offer optional switch for reversal. Stopping of a motor with a one-way control should be done by dynamic braking, some controls offer the Forward-Brake-Reverse switch for this purpose too.
	Regenerative Regen controls are designed to easily operate the motor in forward and reverse directions without motor lead reversal. A separate set of SCRs is used for each direction. With a regen control, stopping is controlled by using the motor's regenerated voltage sent back to the AC line.
