A flexible solution ideal for large machines or for machines with limited space for the cabinet. The integrated servo motor comes with local I/O for easy wiring of distributed signals and also has a built-in EtherCAT port that offers full integration within the System Automation Platform.
The full metal construction ensures immunity from external electromagnetic interference while the sealed, IP67 certified rear drive compartment protects sensitive electronics and sensors from dust and moisture. The RADIX drive system uses DSP based electronics to implement Field Oriented Control (FOC) algorithms - providing silent, efficient, and stable motion control. RADIX servo system works with the Servo Configurator software to provide an intuitive and easy to use interface for configuring system parameters.
All RADIX inputs are optically isolated to protect against unintended damage. These inputs are designed to accept differential as well as single-ended signals. Using the Servo Configurator software, it is possible to individually modify the behavior of each input when the opto-isolator changes between its “on” and “off” state. The following shows examples of some of the possible wiring schemes.
The ALM output is also isolated using opto-isolators. The theory of operation is similar to inputs except the direction is opposite. The examples below should controller circuits with their own opto-isolator inputs, however, these can be omitted and replaced with simple digital inputs with appropriate pull-up or pull-down circuits.
RADIX Servo Configurator is a desktop application specifically designed to help configure RADIX series servos as well as assist in tuning and monitoring the servo. Servo Configurator is free to download and use, please contact your sales representative for more information.
Through the overview screen, one can access the IO Configuration, Parameter Management, Fault Record, and Advanced Settings interfaces. Hovering the cursor above “?” signs shows helpful information about the relevant interface.
First select the wiring scheme that will be used to connect the RADIX servo and controller. Then in the I/O Options section, select the settings for individual input/output signals and check the Signal Truth Table to see if the results match the desired behavior. Finally, click Commit Changes to save the settings to the servo.
Commit Parameters instructs the servo to save all parameter values to non-volatile memory. Reset Parameters to Default will reset all parameter values to their factory default values. The Import/Export function allows the user to export current parameter values to a configuration file. This file can then be imported back at a later date or onto a different servo.
Up to 15 faults are recorded. If more than 15 faults occur, the oldest fault record is lost. Fault records are retained even after RADIX servo is powered off. If a fault is currently triggered in the servo, it will be displayed as the Current Fault. Note that tuning and monitor functions cannot be performed by the servo while in a fault state. Fault records can be wiped from the servo by clicking Clear Fault Records.
The power indicator configuration allows the user to change the behavior of the power LED from its default constant on state to other blinking states. Fault settings allow the user to change thresholds of various faults.
The tool can be accessed from the File menu at the top left corner of the main Servo Configurator window. With Gang Programmer Tool the window open, first select a configuration file. Configuration files are created by using the Parameter Management interface to export a set of parameters from an existing RADIX servo.
Tuning can be performed whenever the servo does not behave well within its installed system; this may include oscillations, overshoot of position or speed, sluggish response, and more.
