USER'S GUIDE MOTION CONTROL SYSTEM, MSC-250
1 - 2 DESCRIPTION MARCH 2003
3. Actuator: The actuator supplies the signal which causes the controller
to initiate the specified sequences. It may be a separate
device or part of a computer program from the Input Device.
4. Power Supply: The power supply converts AC input power into DC power
and conditions this secondary power so it can be used by
the drive.
5. Drive: The drive (also called a servo-amplifier) amplifies a low
voltage velocity command signal from the controller into the
necessary voltage and current to cause the motor shaft to
rotate. The amount of power and polarity (positive or
negative) of the voltage supplied to the motor is determined
by the command signals from the controller.
6. Motor: The motor is the device being controlled by the indexing
system. The system controls the amount and speed of
motor shaft rotation.
