Chapter 4 Operation
Getting Started
Caution
Although the module can tolerate up to 8kV of air discharge, it must be treated as an ESD sensitive device. When
handling the device, anti-static precautions must be taken and suitable and discharge appliances must be worn.
Do not expose the Stage to magnetic fields as this could affect the positioning and homing sensor operation.
When power is applied, do not connect or disconnect the ribbon cable connecting the USB/PSU adapter to the Stage
PCB. Always remove power before making connections.
Warning
If the device is operated over a prolonged time period, the motor housing may become hot. This does not affect motor
operation but may cause discomfort if contacted by exposed skin.
1. Perform the mechanical installation as detailed in Section 3.2
2. Connect the handset to the stage if required.
Caution
The unit is easily damaged by connections with incorrect polarity. Pin 1 of the connector on the PCB is marked with
an arrow (see Figure 4 and Figure 6.) which should be adjacent to the red wire in the connecting cable.
3. Connect the stage to a 5V supply and switch ‘ON’. (A 5V PSU is supplied with the ELL10K).
4. Connect the unit to your PC if required, and wait for the drivers to be installed.
5. Home the stage. Homing is necessary to align the sensor and establish a datum from which all future moves are
measured.
4.1.1 Position Error Compensation
The stage has a positioning error compensation algorithm. When moving from one position to another, the stage detects the
error between the requested and actual positions and will calculate an error compensation value, which is then applied to the
next movement. A default compensation value is loaded on boot up, then the optimum value is calculated within the next 2 to 6
motions. Subsequently, the calculation is continually updated and is applied automatically.
