The warranty period is 12 months after purchasing and is valid only
if all operational conditions and scheduled maintenance are strictly
followed.
1. General terms
1.1. In case of product acquisition as separate components, Seller
guarantees working ability of every component, but does not
assume responsibility for the quality of their joint work (mismatch
of components). If you have questions please consult our technical
support team.
1.2. Seller does not guarantee compatibility of the purchased product
with the one that Buyer already has or bought from third parties.
1.3. Product’s component parts and configuration can be changed by
manufacturer without notice due to the product consistent technical
improvement.
2. Conditions for warranty acceptance
2.1. The product is accepted only in the same completeness of set as it
was purchased.
3. Warranty service procedure
3.1. Warranty service is performed by testing the claimed product
defect.
3.2. If the defect is proved, warranty repair is carried out.
4. We do not assume any responsibility for glass, electric lamps,
starters and expendable materials as well as:
4.1. Damaged product caused by inappropriate transport and store
conditions, wrong connection, operation in abnormal (off-design)
mode, or in conditions which are not manufacturer-supplied (including
temperature and humidity out of limits of recommended range), having
damages due to third-party circumstances (voltage jumps, natural
disasters, etc.), also having mechanical or thermal damages.

Phase current adaptation (stepper motor smooth running) is carried
out by PHASE TRIM potentiometer when vibrations and uneven
stepping at low revs is found.
Adaption strategy is as follows:
1)
A potentiometer is set to the extreme left position (minimum value).
2)
Stepper motor is connected, voltage is supplied, vibration frequency
is set up by STEP frequency generator.
3)
When smoothly rotating PHASE TRIM potentiometer clockwise, the
vibration reduces.
You may fail to reduce vibrations totally because of stepper motor
specifics.
When removed from one frequency, vibrations can appear in another
frequency. Therefore it is necessary to choose the most suitable way of
setting.
The driver allows to divide electronically physical stepper motor step -
4, 8, 16 and 32.
Thus positioning accuracy is higher. Step division mode is called
microstep division. This mode allows to reduce stepper motor
resonances at low revs.
It is recommended to use PLD57 driver in step division 1:8, 1:16 or
1:32. In these modes stepper motor rotates as smooth as possible, low-
frequency vibrations are minimal, automatic compensator of stepper
motor mid frequency resonance works best.
Switching of step division mode is performed with help of jumpers JP1,
JP2 which are located inside the device (you should remove the cover)
Step division choice must be performed only when driver supply is OFF.
