Hi everyone, We have recently tried Rexroth linear SSI encoder at 840d sl system with Siemens linear motors and Rexroth linear scales. Once we set SSI encoder parameters , encoder frequency limit error occured. I increased encoder frequency limit (which is 300KHz default) to 10MHz. After that we try to optimize the linear motors but not able to increase axis parameter 32200_POSCTRL_GAIN. Before this setup, we had Drive Cliq Rexroth absolute linear encoders and we were able to set 32200_POSCTRL_GAIN parameter --> 20 and there was no problem. Eventually, we suspect baudrate in Drive Parameter p427((Default 100KHz) and increase it to 500KHz. Now we are able to increase 32200_POSCTRL_GAIN to 20 but there anormal noise at linear motors, like high frequency noise. I need help to set encoder parameters correctly, because I think there is a problem at encoder parameters which is leading positioning incompatiblity between encoder and SME125 module. Drive Parameters
Encoder Data Coding--> Binary Number of bits (position) --> 25 Parity --> straight Error bit --> yes Warning bit --> yes Interface resolution /μm --> 1 Max. clock frequency --> 2 MHz |
