Functions
● Setting of the current value by means of dip-switches.
● Selection of the number of step/revolution by means of roto-switches.
In order to maintain compatibility with traditional drivers,
the number of step/revolution have been emulated through
software, the current regulation is always sinusoidal.
● Possibility to select five user functions:
1 - enabling of motor stall detection.
Reading the motor BEMF, LWC drivers detect without encoder the step loss, showing alarm status with the Fault digital OUT and a LED sequence.
2 - Step/Direction or Clock-Up / Clock-Down control mode.
3 - enable input management (safety control).
4 - 30% or 70% automatic current reduction (still motor).5 - enabling of “Clock Test” function, useful during the driver’s installation, which shows the right presence
of the clock signal through status LED flashing.
