Mode Description

SECTION 7 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.
