10 Protection functions, setup
When the protection function operates, the driver switches off
stepper motor coils, red signal ERROR (LED2) flashes on. The driver
restores its work after alarm cause removal and switching off/on power
supply.
In some cases by interturn short-circuit of stepper motor coil,
short-circuit protection may not work because there is no exceeding
of permissible alarm current. This happens because under such coil
short circuit resistance does not equal 0 and the driver maintains the
specified current.
The warranty period is 12 months after purchasing and is valid only
if all operational conditions and scheduled maintenance are strictly
followed.
