PROFILE Trajectory Parameter

ACTION: Determines how the motor’s speed changes.

PROGRAM SYNTAX: PROFILE(axis)=expression

PROFILE=expression1, ... , expression8

PROFILE(axis, ... , axis)=expression, ... ,expression

PROFILE(axis) - used in an expression

REMARKS: The axis specifies the axis number (1-8).

The expression specifies the profile setting (1-32).

Speed changes require a period of accel/decel to increase/decrease the

motor’s speed. The Profile value determines how the accel/decel is ap-

plied. The MX controller has 32 choices. A profile setting of 1 results

in a “Trapezoidal” profile. This yields the minimum move time. Settings

2-32 yields “S-curve” profiles with varying degrees of “S”. The higher

the profile setting, the more “S” like the profile. Move times with profile

settings 1-32 are from 1 to 31 ms longer respectively than those with a

setting of 1. The “S-curve” profiles usually results in smoother motion at

the expense of longer move times.

EXAMPLES: PROFILE(1,3)=16,32

axis 1 profile is set to a value of 16 and axis 3 profile is set to 32.

PROFILE(2)=10

axis 2 profile is set to a value of 10.

PROFILE=16,,32

axis 1 profile is set to a value of 16 and axis 3 profile is set to 32.
