Mode Description
SECTION 8
Closed Loop
Speed Mode
This section discusses the AX500 Close Loop Speed mode.
Mode Description
In this mode, an analog speed sensor measures the actual motor speed and compares it to
the desired speed. If the speed changes because of changes in load, the controller auto-
matically compensates the power output. This mode is preferred in precision motor control
and autonomous robotic applications.
The AX500 incorporates a full-featured Proportional, Integral, Differential (PID) control algo-
rithm for quick and stable speed control.
Selecting the Speed Mode
The speed mode is selected by changing the Motor Control parameter in the controller to
either:
• A and B Closed Loop Speed, Separate
•
A and B Closed Loop Speed, Mixed
•
A Closed Loop Speed, B Position
Note that in the last selection, only the first motor will operate in the Closed Loop Speed
mode.
Changing the parameter to select this mode is done using the Roborun Utility. See “Load-
ing, Changing Controller Parameters” on page 134.
