Verify the installation
- Check all connections : Power supply, Stepper motor and control logics.- Make sure that all settings are correct for the application.- Make sure that the characteristics of the DC power supply are appropriate for the drive.- If possible, remove the load from the rotor of the motor to avoid wrong movements and eventual damages.- Enable the current in the motor (without STEP Clock) and, if possible, verify the presence of the Holding Torque.- Execute a movement of some steps and verify if the rotation direction is the desired one.- Disconnect the power supply, connect the load on the motor and check the full functionality.
Company Profile

Taking advantage of the proactive climate of the 70s, in 1977 the engineer Felice Caldi, who had always been a passionate builder and inventor, founded an innovative company, operating internationally in the field of software for industrial machinery.
Since then, this small company based in Lodi has enjoyed continuous successes related to innovative products and cutting edge "best in class" technologies in the field of industrial automation, as proven by the many patents filed during the years as well as the important awards given to it by the Chamber of Commerce of Milan and of the Lombardy Region.
The company, thanks to its successes over time, has grown considerably, expanding its sales network abroad and opening another company in China to manage the sales flow in the Asian market.
Ever attentive to the dynamics and needs of the automation market, constantly evolving and continually seeking technological innovation, Ever Elettronica has been able to respond to all the technological challenges that have arisen over the years, providing solutions able to make its customer's machines more and more performing and highly competitive.
And it is precisely to underline the importance and the uniqueness of every single customer that we design, with care and dedication, highly customised automation solutions, that are able to perfectly meet any request, both regarding software and hardware.
Our team of mechatronic engineers can indeed customise the software with specially designed firmware, and it can also adapt the motor by customising, for example, the length of the cables or the diameter of the crankshaft and the IP protection degree, all strictly based on the customer's technical specifications.
