EA180 Series Servo Drive Users Manual Table 3-6 Description of position pulse input signal The pulse command can be input using open collector mode or differential mode. The maximum input pulse frequency of differential input mode is 500Kpps, and that of open collector mode is 200Kpps. A certain filter time needs to be set for the pulse input terminal to prevent interference signals from entering the servo drive to cause motor misoperation. For filter time, see the description of P1-15 function parameters. Different command input pulse modes have different timing and time parameters, as shown in Tables 3-7 and 3-8:
