Please, I will be grateful if you can help me, Thanks in advance, Best regards,

Chapter 4.5.1 Overview of the interfaces on the front and upper side ⑤ Keep the switch in the "Vector" position. The inverter is not functional in the "Servo" setting.

Do I have to change the CU and the PM?, or Can I use the PM and change te CU? I will be grateful if you can help me, Thanks in advance,

In case of a permanent synchronous motor in sensorless operation the CU310-2 which could operate with PM240-2 too is the right choice.
