1.2. Basics of Operation
The RMC is a high-performance motion controller. It has many advanced features, yet is easy
to use and can be set up quickly due to features such as Scale and Offset wizards and
Autotuning.
This topic describes the most basic concepts of using the RMC.
Motion
Motion control falls into two camps: open loop and closed loop.
Open loop means that a control signal (called Control Output in the RMC) is given to the
system to move it without regard to the feedback of the system, such as position,
velocity, pressure, etc. Open loop control is not very precise.
Closed loop means that the controller uses the feedback to determine how much Control
Output to give to the system to move it to the desired position. Closed loop control can
be very precise if the system has high-resolution feedback and a good actuator.
The RMC provides both open loop and closed loop control.
Open Loop control is fairly simple. Just issue an Open Loop Rate (10) command to the
RMC to move the axis in open loop control. See the Issuing Commands section below
for details on issuing commands.
Closed Loop control is more complex. The RMC is all about closed loop motion control.
