3 Click the Trajectory button in the Axis Control window. The Trajectory dialog box appears.
4 In the Profile mode list, select Trapezoidal.
5 Enter motion profiles for deceleration, acceleration, velocity, and destination position (Position 1) that are
safe for your system and will demonstrate proper motion.
6 Click Go and confirm that the motion occurred in a stable and controlled fashion.
Congratulations! First-time system verification for this axis is now complete.
Pro-Motion provides various selectable units for distance and time, but defaults to units of encoder counts (or
pulses for step motors) for distance and seconds for time. This means the default units for velocity are counts/sec,
and the default units for acceleration and deceleration are counts/sec
2
. So for a motor that has 2,000 counts per
rotation, to perform a symmetric trapezoidal move of 25 rotations with a top speed of 5 rotations per second and
with an acceleration time of two seconds, the parameters in the Trajectory dialog box would be set as follows:
Deceleration: 5,000 counts/sec
2
Acceleration: 5,000 counts/sec
2
Velocity: 10,000 counts/sec
Position 1: 0 counts
Position 2: 50,000 counts.
