Spindle motor is asynchronous motor with 3 stage gear ratio. Its RPM is also configured & machine is in use from last 2 years. In case of auto gear change whenever speed change is there, gear stage is automatically selected. While gear change, spindle oscillates at certain RPM sothat gear shiftssmoothly& gear change completes. I would like to know whether this reference or set point is variable?, if so which is the parameter no? In other word can user vary this oscillation speed of spindle motor?

There you can change the Speed of it. 35410 $MA_SPIND_OSCILL_ACCEL 35430 $MA_SPIND_OSCILL_START_DIR 35440 $MA_SPIND_OSCILL_TIME_CW 35450 $MA_SPIND_OSCILL_TIME_CCW If DB...DBX17.4 is high at the time of oscillation. You have to edit the time it in PLC
