I am working with an LS IS brand servo driver and servo motor. I have some difficulties with getting it to work.

Full manual

I have to mention that I don't have knowledge in servo motors.

I am using a Cypress PSOC (instead of an PLC) to generate 800Hz signal to drive the motor.The main idea is that the motor should turn a whole circle if the driver recieves 800 pulses.

I connected all the power wires(one phase 240V),encoder wires,motor connectors(U,V,W). I also connected the digital control signals. Here you can see typical wiring for Position Operation Mode

The servo motor is rotating but not at the speed i wanted(it doesn't complete a full circle in one second,but the 800Hz is provided,I checked it with oscilloscope,and also in the servo menu St-06).It rotates really slow,like it would took couple of minutes to make a full circle. Because the Cypress PSOC provides a square wave signal the servo controller is working in Position Control mode. I have tried to increase the signal frequency but nothing has changed much.

So if anybody can help me I would be thankful.

Any numbers like :

• P0-00
• P0-26
• P4-00

represents a menu entry that can be changed
