Chapter 5 Troubleshooting and FAQ
5.1. Frequently Asked Questions
Bi positional slider is moving back and forth after power up
If the digital line “bw” is driven low before powering up the bi positional slider, the module will go into calibration
mode. Remove power to exit calibration mode. Keep line tight up to 3.3V or 5V rail during power up or use a serial
communication line instead.
Bi positional slider not moving
Check power supply lines ratings (polarity, voltage drop or range, available current) or reduce cable length.
Check module is not in boot loader mode (power cycle the module to exit boot loader) consumption must be higher
than 36mA at 5V.
Bi positional slider switching time increased / max load decreased
Check power supply voltage provided on J2 connector, increase voltage within specified limits if voltage drop along
cable goes below 5V during system operation.
Clean the moving surfaces. To avoid grease contamination, do not touch the moving parts.
Temperature change may affect bi positional slider performances. A frequency search procedure using provided
software will compensate frequency as needed (required current could reach 1.2A during frequency search, use an
addition 5V 2A power supply).
Integrators should search for optimal frequency on every power up sequence
(commands “s1”, “s2” see ELLx protocol document)
How do I restore the factory (default) settings
Factory settings can be restored during the start up (calibration) test – see Section 3.6.
What is the typical product life time
ELL6 product life time is restricted by the wearing of moving surfaces and the motor contact as motion is started
(due to resonance build up) and performed (due to friction). Therefore, life time is expressed both in km and millions
of operations, whichever comes first will depend on the module usage. Operation and km are related by the module
travel of 31mm, with a minimum lifetime of 100km relating to 3.3 million operations.
The unit is not designed for continuous operation. Users should aim for a duty cycle of less than 40% wherever
possible, and never exceed a duty cycle of 60% for longer than a few seconds.
Handling
The stage and interface board are robust to general handling. To ensure reliable operation, keep the surface of the
plastic track contacted by the motors free of oils, dirt, and dust. It is not necessary to wear gloves while handling
the linear stage, but avoid touching the track to keep it free of oils from fingerprints. If it is necessary to clean the
track, it may be wiped with isopropyl alcohol or mineral spirits (white spirit). Do not use acetone, as this solvent will
damage the plastic track.
