09. Protection functions
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.
4.2. The product with traces of foreign objects or substances impact,
including dust, liquids, insects, also objects having extraneous
inscription.
4.3. The product with traces of unauthorized tampering and (or) repair
process (traces of opening, home-made soldering, elements changing
etc).
4.4. The product with self-diagnostic function that shows improper
exploitation.
4.5. Technically complex product in respect of which assembly
and integration and start-up works were not performed by Seller
specialists or by recommended organizations, except in cases directly
regulated under goods documentation.
Max shaft rotation frequency is 30 cycles per second (under greater
rotation frequency, the torque on the step motor shaft becomes
minimal, you can reach such speed only by rotating stepper motor with
unloaded shaft under laboratory conditions, produced EMF under such
high turnover can result in failure of driver power part so for safety
reasons the driver turns off). For step division 1:1 max frequency STEP
is 6 kHz, 1:2 — 12 kHz, 1:8 — 50 kHz, 1:16 — 100 kHz. When protection
operates the driver turns off stepper motor coil, green LED goes out.
The driver restarts after OFF/ON supply voltage and error-cause
removal.
The driver allows to divide electronically physical stepper motor step -
1, 2, 8 and 16.
Thus positioning accuracy is higher. Step division mode is called
microstep division . This mode allows to reduce stepper motor
resonances at low revs but when using microstep the stated time
on stepper motor shaft is reduced. Switching of step division mode
is performed by dip-switch SW1, SW2. Step division choice must be
performed only when driver supply is OFF.
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).
