Button Operation - THORLABS TIM101 User Manual

4.4 Button Operation

The buttons on the front of the unit can be used to control the motor in a number of
ways, as described below.
If the actuator is driven into its end stops, the motor may stick and may
not respond to subsequent motion demands. If this is the case, turn the
adjustment knob of the actuator manually to move the device away from
its end stop, then the motor should move normally.
4.4.1 Zeroing
To establish a datum from which subsequent moves can be measured, move the
motor to the required zero position, and then press and hold both jog buttons for 2
seconds.
The counter can also be zeroed by clicking the ZERO button on the GUI panel (see
Section 5.4.), or by calling the SetPositionSteps method and setting the position to
zero (see the APTServer helpfile for more details).
4.4.2 Go to Position
In 'Go To Position' mode, each front panel button can be programmed with a different
position value, such that the controller will move the motor to that position when the
specific button is pressed. These 'taught' positions can be set through the software
GUI - see Section 6.3.2.
In addition to entering values in the Pot/Buttons Tab as described in Section 6.3.2.,
when operating in 'Go To Position' mode it is possible from the front panel, to save
the current position as the 'Go To Position' value.
To save the current position as the 'Go To Position' value, press and hold the
required button for 2 seconds.
When the button has been programmed the 'Active' LED on the unit will flash five
times. Typically you would use the pot to move the motor to the required position and
then 'teach' the button by pressing and holding it.
The move can be stopped at any time by pressing either of the move buttons.
This mode of operation is enabled by setting the 'Button Mode' parameter to 'Go To
Position' on the Pot/Buttons settings tab - see Section 6.3. for further information.
4.4.3 Jogging
The front panel buttons can also be configured to 'jog' the motor. This mode of
operation is enabled by setting the 'Button Mode' parameter to 'Jogging' on the 'Pot/
Buttons' settings tab - see Section 6.3. Once set to this mode, the jogging parameters
for the buttons are taken from the 'Jog' parameters on the 'Move/Jogs' settings tab -
see Section 6.3.
