14.4.6 BP2P Mode:Basic Point to Point:Description of Curve
※ 14.4.6.0 BP2P Mode:Basic Point to Point:Description of Curve
The following picture (captured by Soft-Scope) is a typical waveform that shows a complete
Point-to-Point operation cycle. The cycle is started by a trigger signal (in this example DI-01 is chosen as
P2P Trigger). After trigger command issued, a motion profile including Velocity (Vcmd), Acceleration
(Acmd) and Position (Pcmd) commands are generated simultaneously. After the Pcmd reaches the
desired target position, the motion controller generates a P2P Ready status (in this example, DO-01 is
chosen as P2P Ready).
Of cause, the Pcmd, Vcmd, and Acmd must follow the basic equations:
In the “Note” window, it records some critical settings for this motion curve.
S-curve: defines the change rate for the Acmd .
Ramp Rate: defines the rate of acceleration and deceleration.
Travel Length: records the desired target length or position for this particular motion profile.
Pr.318=Motor-Side-PPM, is the conversion factor between Metric-Length unit and equivalent
motor pulses.
Maximum Speed: There is another setting not shown here, which is the maximum running speed
limit is 1000rpm.
