7. Motion Control Overview
Important Note:
All the commands described in this section are interactive commands
and are not analogous to stand-alone commands. Refer to the “Standalone Language
Specification” section for details regarding stand-alone commands.
Motion Profile
By default, a trapezoidal velocity profile is used. See Figure 7.0.
Figure 7.0
High speed and low speed are in pps (pulses/second). Use HSPD/LSPD commands to
modify the high speed and low speed settings.
Acceleration and deceleration time are in milliseconds. Use the
ACC/DEC command to
modify the acceleration and deceleration values.
S-curve velocity profile can also be achieved by using the
SCV command. See Figure
7.1.
Figure 7.1
Notes:
By default, the deceleration is defined by the value set in the ACC parameter. In order to
decelerate using the value set in the DEC parameter, set EDEC to 1.
The minimum and maximum acceleration values depend on the high speed and low speed
settings. Refer to Table A.0 and Figure A.0 in
Appendix A
for details.
