4.4 Measurement

The default measurement unit on the controller is "bit", or a single microstep on the actuator.
However, the controller is capable of displaying position data in microns ("um") for T-LA, T-
HLA, and T-LS series of actuators and any device for which the leadscrew pitch and motor step
configuration work out to be 128 bits = 12.7 um.
On the measurement screen, the preferred unit of measurement is displayed with square brackets
around it. Pressing the button next to the units of measurement will toggle the square bracket.

Press "Back" or the rotary knob to escape back to the main control screen which now shows um.

Step
Note that the communication between the controller and the actuators are still done in bits. The
controller converts from um to bits before sending the correct amount of relative movement to
the actuator, and converts from bits back to um after receiving a reply of the position from the
actuator after it finishes moving. Originally the display was showing actuator 1 at 1000 bit
position. The controller now displays the position as 1000 x 127 / 128 = 99.2 um.

4.5 Reset

This command simply resets the T-CON3 controller. The controller will go through power-up,
display the splash screen, and attempt to initialize the actuators.

4.6 About

This command displays the splash screen, same screen displayed on power-up or reset. The
controller model number (T-CON3) is on the left and the firmware version is display on the
right. On the bottom line is the "Back" button to go back to the previous menu.
