PMAC Quick Reference Guide To be able to reach the desired velocity, a longer move can be performed split into two sections. The first move will be executed using a suitable TA to get the motor to move from rest. The second move will have a lower acceleration time TA in order to decrease the move time TM and so reach the programmed feedrate. OPEN PROG 1 CLEAR LINEAR INC TS0 F40 TA100 X3 TA75 X3 CLOSE 5. All the previous analysis was performed assuming a zero S curve component. A move executed with an S curve component will be similar in shape but with rounded sections at the beginning and end of the acceleration lines. Motion Programs 53
