When driven by a motorized stage controller driver, it is possible to find the amount moved by using the following calculations:

Amount moved = Motorized stage [Resolution] × [Number of Pulses] generated by the controller driver

As the motorized stage resolution may vary depending on the particular model, the amount moved per pulse generated by the controller driver can also vary.
For example, if you want to move an X stage by 10mm with a resolution of 0.002mm, based on the above formula, the number of pulses required can be shown to be:

Number of pulses = 10mm ÷ 0.002mm = 5,000 pulses

Our company’s QT-B series controller drivers are packed full of useful features that can be utilized even during manual operation.
These features include step feed (STP mode), where a preset number of pulses can be generated.
For example, if you want to move an X stage incrementally in 1mm steps with a resolution of 0.004mm, it is set to 250 pulses when in STP mode.
After that, if the operator presses a movement button on the control box, the stage will move 1mm for each press. The movement buttons can work in both the [+] and [-] directions. Therefore, it is very easy to carry out types of operation such as: After 10mm of displacement with a 1mm pitch in the plus direction, it returns 5mm in the minus direction.

Jog control (JOG mode), where the stage continuously moves as long as the control box movement button is pressed down, can be used to move the stage to any arbitrary position. However, as the controller driver coordinate value is displayed in terms of the number of pulses, after jog operation is completed, it is not possible to know how far from the zero position the stage has moved unless it is calculated separately.
By having preset values for ‘resolution’ and ‘unit display’ of stages connected to QT-B series controller drivers, with one simple press of the ‘DISP’ button the operator can switch between displaying the number of pulses to displaying the set unit. This allows the operator to easily find the stage displacement amount without the need for performing calculations.
