Motion Controller Features

RMP, RMP+, and eRMP+ EtherCAT Motion Controller offer many motion and IO features.

R

On-the-fly Trajectory Modifications

Point to Point and velocity motion trajectories can be modified on-the-fly, including positions, velocities, accelerations, deceleration, and jerk percents.

R

Point to Point Motion

Moves from current command position to a new position: Trapezoidal or S-Curve Move.

R

Pre-Defined Homing Routines

Execute pre-defined or custom homing routines.

R

Gantry

Multiple control schemes are available including algorithms where separate PID’s control the linear and Yaw Axis.

R

Velocity Motion

Maintain constant velocity between points. An example is Conveyor axis. The ability to gradually ramp up or ramp down the velocity.

R

Streaming Point Motion

Stream of raw data points which represent an entire motion profile. PT, PVT, PVAJT motion streaming types are available.

R

IO Trigger Based Events

Configure input comparisons to trigger outputs or other events. Conditions are monitored at the firmware level. When the condition is true, the configured response is generated.

R

Record Real-Time Data

Provides a mechanism to collect and buffer any data in memory. The data is later polled via interrupt-based events.

R

Camming

The position of a slave axis is mathematically linked to the position of a master axis. Create a table and start with camming.

R

Electronic Gearing

Configure an axis’ commanded position to be geared off of another axis.

R

Path Motion

Geometric path motion allows complex 2D and 3D paths to be specified using simple geometric elements (arcs and lines).

R

Interrupt Handling

Provide the ability to interrupt the host at a specified frequency, where the frequency is a multiple of the controller’s sample rate.

R

High Speed Position Capture

Latch the position counters in the FPGA and are read directly by the controller. The ability to latch axis’ position based on one or more source input triggers.

R

Intelligent Diagnostics

Add cable break, drive, or motor fault warning/messages directly into software.

R

Dual Loop Feedback

Enable secondary feedback.

API Classes



Axis Class

Represents a single axis of motion control. This class provides an interface for commanding motion, reading trajectory parameters, configuring filter (control law) parameters, homing, limit switch configuration, motor configuration, position capture, electronic gearing and node information.



MultiAxis Class

Provides an interface to a group or collection of axes. Use the MultiAxis class when coordinated, synchronized or path motion is required.



MotionController Class

Provides an interface to general controller configuration, firmware upload/download, network, and data recording.



IO Class

Provides an interface to an I/O Node. An I/O node can have various combinations of digital or analog inputs and outputs.



IOPoint Class

Provides a common interface to any I/O point, regardless of where it resides in the network (Motion Controller, Axis, or I/O Node).



RsiError Group

Is thrown as an exception by all RapidCode classes. It contains and error number, and a text message which describes the error. Throwing exceptions can be disabled on all RSI classes. If throwing exceptions is disabled, a log of RsiErrors can be accessed.
