To use the CP1L's motion functions (PULS, SPED, PLS2...) you need the transistor output plc, not the relay type. Relays don't like giving a 50KHz pulse train

you need high speed pulse(PTO/PWM) to control stepper/servo motors so you really need a transitor-output type PLC. What is the brand/model of your servo motor?

What do you want the PLC to do to the servo motor, control what, start, stop, speed matching, move x amount?

I've never seen a 25hp servo motor.

re:rich1955..

i mean 25W only..the servo motors are speed controlled, it will be attached to a conveyor belt, in which items will be loaded..the plc will basically start/stop the motors..anyway, there is no sequence of motors involved in this programming..

It is difficult for anyone to help you when the motor/drive specification "Panasonic PAC-MV" does not exist on the Panasonic Automation website. The smallest sevo motor they make is 30W but you say you are using a 25W unit.

If you can be more specific about the unit you are using [post a link to the motor and drive] and exactly what you are trying to do then you will get useful feedback to your questions.

S--- in S--- out.

re:bits n bytes

but the it does exist in their catalogues..it is a speed control motor, gear type..actuali, the motor is hard to find on the net..anyway, i wil post the specs of the servo motor we will be using:
80A, 25W, 200V, 1.5 kg, 90 rpm..
