Hi, I have 2 things in mind: 1. Did you set up the encoder data correctly in the Technology object configuration? Check out this FAQ: https://support.industry.siemens.com/cs/de/en/view/109747183 It says that for the 2500TTL encoder you need to set "increments per revolution" = 2500 and "Bits in Gx_XIST1" = 2. If these values are not correct the actual speed and position of the motor cannot be tracked correctly and following errors could occur I think. 2. did you perform a One Button Tuning to optimize the control behavior of your axis? Here I am not sure whether I should recommend you to do so because you use telegram 3 which is no isochronous communication (I know PLC 1200 cannot do isochronous operation so this is not an option to change). Maybe you did a One Button Tuning and exactly this is the problem now with non IRT communication because the drive has maybe activated torque precontrol etc. and this leads to noise. |
