Frequency Search
Due to load, build tolerances and other mechanical variances, the default resonating frequency of a particular motor may not be
that which delivers best performance. A frequency search can be performed using the Main GUI panel in the ELLO software, or
by using the serial communication line (SEARCHFREQ_MOTORX message), which offers a way to optimize the operating
frequencies for backward and forward movement.
This search can also be performed manually by restoring the factory settings as described in section 4.5.
Periodic Cycling of Devices Over Full Range of Travel
Caution
Periodically, devices should be moved over the full range of travel, from one end to the other. This will help minimize
the build up of debris on the track and will prevent the motors digging a groove over the most used area of contact.
Typically, a travel cycle should be performed every 10K operations.
Restoring Factory Settings
Factory settings can be restored during the start up (calibration) test as follows:
1. Remove power from the stage.
2. Press and hold the BW button (do not release until item 6).
3. POWER UP
4. WAIT for red led to switch off
5. Press and hold the FW button to request a reload of factory values (do not release until item 7 is complete).
6. Release BW to reboot
7. Continue to hold the FW button until the stage stops moving and the red LED switches off, then release.
8. Press the BW button to home the stage.
Simultaneous Movement of Devices
If more than one device is connected to the comms bus, movement of the devices can be synchronized. This can be achieved
either by using the handset connected to each stage, or by software. See the protocol document for details on how to use the
‘ga’ message to synchronize moves.
