This is dedicated for European customers.
Mainly PNP is used exclusively in Europe, some machines in Middle East, but America and Asia and completely NPN.
That’s why in the first place our servo drive inputs are only compatible for NPN PLC output (like our Delta PLC’s).
But what happen If my customer is really used to work with his European brand PLC, but he wants to test our servo drives?
In this case we suggest the following PNP connection for ASDA-A2.
Furthermore, in the attached file you will find all the other suggested connections for the other servo drive series.

Dear sir,
I have DVP12SE series PLC PNP type, I need to connect servo drive to it. can we able to connect a servo drive with PNP plc.

hi, i did like you above but i use MCU to generate pulse and sign for ASDA-B( the input type is NPN) i connect MCU pin and ASDA-B via opto(P521) (follow the diagram connection in manual) the resistor is 1Kohm/0,6w but when i start MCU to make pulses and sign then the resistor which is connected to sign pin is very hot, i dont know why ? pls explain for me

the 1K ohm to to protect the Servo Input.
If it’s so hot is because something is not connected as it should be, please recheck all the conexions

PLz reply.
I have dop B series 200 hmi and it is password protected read as well as write password protected.
plz support how to reset HMI DOPb-7s200

Not possible to crack password.
Test the default passwords 12345678 and 87654321
And If they don´t work, I recommend to contact with machine maker.
