11.1 S7-1500 Motion Control V2
Description
Technology object
Start of the job with a positive edge
Setpoint speed / setpoint speed for the motion pro-
cess
("Velocity" = 0.0 is permitted)
Acceleration
Value > 0.0: The specified value is used.
Value = 0.0: not permitted
Value < 0.0: The acceleration configured in "Tech-
nology object > Configuration > Extended parame-
ters > Dynamic defaults" is used.
(<TO>.DynamicDefaults.Acceleration)
Deceleration
Value > 0.0: The specified value is used.
Value = 0.0: not permitted
Value < 0.0: The deceleration configured in "Tech-
nology object > Configuration > Extended parame-
ters > Dynamic defaults" is used.
(<TO>.DynamicDefaults.Deceleration)
Jerk
Value > 0.0: Constant-acceleration velocity profile;
the specified jerk is used.
Value = 0.0: Trapezoid velocity profile
Value < 0.0: The jerk configured in "Technology
object > Configuration > Extended parameters >
Dynamic defaults" is used.
(<TO>.DynamicDefaults.Jerk)
Direction of rotation of the axis
0 The sign of the velocity specified at the
"Velocity" parameter defines the direction
of rotation.
1 Positive direction of rotation
Value of "Velocity" is used.
2 Negative direction of rotation
Value of "Velocity" is used.
