Motion control typically refers to systems with accurate position/velocity/torque capabilities operating in either open or closed loop mode. Open loop stepping drives send motion commands to stepper motors, but receive no information about the result. Closed loop servo systems have feedback devices at the motor shaft to verify or adjust the resulting motion.
The AutomationDirect SureServo family of brushless servo systems is fully digital and offers a rich set of features to cover a broad range of motion control applications. There are eight standard servo motors that can be operated in combination with one of three standard servo drives.
The SureServo family includes standard accessories such as: servo motor encoder cables, servo motor power/brake cables, ZIPLink kit for servo drive's CN1 connector that provides for easy connection of external controller and I/O, optional external regeneration resistors, and optional AC input filters.
The PGA series of inline planetary gearboxes has a thread-in mounting style, along with a level of precision and torque capacity that is best in its class. The PGB series of right-angle planetary gear reducers offers similar technical specifications to the PGA series and provides an excellent solution when space and clearance requirements are limited. PGD series gearboxes with compact design and hub style output are ideal for equipment that requires high-speed, high-precision indexing movement.
SureStep® is an open-loop stepping system that provides simple and accurate control of position and speed, and offers a low cost motion control solution with up to 1200 oz-in of torque
Programmable logic controllers (PLCs) or other indexers and motion controllers act as a stepper motor controller to send step pulses and direction signals that are received by the Standard stepper drive to allow very precise motion control.
The Advanced stepper drives also accept pulse inputs, but they also can be commanded by an analog speed signal or by serial communication. The SureStep stepping system series includes:
The SureGear PGCN series is a great gearbox value for servo, stepper, and other motion control applications requiring a NEMA size input/output interface. Features include:
SureMotion motor-ready actuator assemblies, sliding components and accessories.
SureMotion linear motion slides and actuators
