Input signal interface

Input signals are consistent with three lines: (1) Stepping pulse signals of CLK and CLK-; (2) Direction electric-level signal of CWW and CWW-; (3) Offline signals of ENA and ENA-. They have the same interface circuits in the motor (See input signal interface schematic) and independent with each other.

The feature of the input signal interface is that it can be connected with shared positive or shared negative according to users’ need.

 Shared positive connection: Connect the CLK ，CWW ， and ENA separately to the power that control the system. If the current level is just 5V, it can be connected directly. However, if the current is above 5V, there will a current limiting resistor needed outside the motor so as to supply a sustained drive current between 8mA-15mA for the optical coupling inside the motor. Add the input signals through CLK- while the CWW- and ENA- is performing at the moment at a low electric level.

Shared negative connection: Connect the CLK-，CWW- and ENA- separately to the ground interface of the control system (SGND, isolated from the power ground), the 5V input signals will be added by CLK , while this moment CWW and ENA is performing at a high electric level. The interpretation of the current limiting resistor is as the same of the shared positive connection.
