Two inputs signlas are provided which, when not connected, prevent the upper and lower devices in the PWM outputs from being operated by the digital control core. This provides a positive OFF capability that cannot be overridden by the control firmware, or associated hardware components. When both STO signals are activated (current is flowing in the input diodes of the optocouplers), the control core will be able to control the on/off state of the PWM outputs.ModelMax CurrentPower SupplyControl ModeInput/OutputMatched Step MotorEPDO-022.4A15-48VPULSE MODE3 IN/0 OUTNEMA8 TO NEMA17 OPEN LOOPEPDO-044.5A24-48VPULSE MODE3 IN/1 OUTNEMA23 TO NEMA24 OPEN LOOPEPDO-087.8A24-75VPULSE MODE3 IN/1 OUTNEMA34 OPEN LOOPEPAO-044.2A100-240VACPULSE MODE4 IN/1 OUTNEMA34 OPEN LOOPEPDC-1010A24-75VDCPULSE MODE/programmable3 IN/2 OUTNEMA11 TO NEMA 34 CLOOSE LOOPVerify 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.
