i want to maintain a Different velocity in a servomotor by using S7-1200 plc Motion control block is MC_MOVERELATIVE block in one rotation of servomotor....i did axisparameter setting also...
can i change a velocity depend upon degree ofmotor rotation....if not possible....by using which block to maintain it.......

i want to change a different velocity upto reached distance(200mm)....i did a sample program for that operation using a MC_MOVERELATIVE Block to change the velocity of the motor.....but iam facing problem is in forward direction maintaining a as per given velocity but inreverse direction it maintaining a constant velocity (high or low) upto the reached distance....what is the problem....what i'll do for maintaning a variable velocity for forward & reverse movement...thanks ur help????????
