We need to control a servomotor and we are looking for the cheapest model 18.6 N-m / 3000 RPM / 230V / 3 phase for positioning task (including the servo-drive and the servomotor), for this we need help to get the proper model. According to an S7-224XP manual the PTO outputs are 20KHz but in an application manual I found the speed was 100KHz, what is the correct information? Is there examples of how to connect the EM253 position module for the S7-200 with a simotion S110 or s120? Best Regards Orlando Núñez

This FAQ should help you to get S110 working with S7-200. (I think you mean SINAMICS S110, not simotion?) http://support.automation.siemens.com/WW/view/en/26513850 Beware, you need a 330k Ohm (2 watt) Load resistor between PTO output and ground, if you want to control the S110. Otherwise the pulses with more then 40kHz won't detected by S110. regards
