While optimisation of Z axis drive on one of the lathe machine with Simucom I got alarm 25060 (Axis %1 Speed setpoint limitation.) Increased values MD 36210 & MD 36220 & somehow (forcibly) optimistion completed. I would liketo know the probable reasons of this faults/alarm.(both mechanical & electrical). Thanks & regards, DEEP.

Please find the details Error effects: >If the maximum speed setpoint is exceededthen theAlarm 25060"Speed setpoint limitationisoutput. >This alarmoccurs when axis stopped with therapid stop via a speed setpoint ramp. >If the axis interrpolates with other axis, these will by the rapid stop with reduction of the following error. Error Cause: > too high setpoints specified (accelerations, velocites,gain factors) >obstacle in the working area(e.g coming in contact with the work table) > Axis moving uncontolled.... you would have also face in SimocomU >enable missing in Master control PC when axis tunning. Hope this will be useful.... Ekalavya

The machine is under commissioning. 2. Z axis motor is without brake. 3. The alarm is present during optimisation with SimucomU. 4. As such no rapid, jog command tried. Hence no ramp Up or ramp Dn. During optimisation, system itself gievs refernce/command & notes downs the motor (load response) So manualy setting of ramp up-Dn time or set point doesn't come in the picture in my case. Hope you must have got my points. Regards, DEEP.

Ekalavya Posts: 2964 Rating: (473)	Hi.... I would like to ask you... >What is the MAX_Axis_Velocity >Postion Control Gain > Max_Axis_Accelreation are kept? This values are kept proper?...... if the values are uneven it will not get optimized properly. Ekalavya
