6.7.3 Range of values
Range of REAL values
The following applies to all REAL values at the input parameters of the technology
functions:
-1E+12 < REAL value < +1E+12
The restrictions specified in the descriptions of the input parameters also apply.
These values are verified in the integrated technology at the start of motion control
commands. If these values ranges are exceeded, an error message is output at the
technology DB and at the technology function.
Range of values for dynamic parameters at the technology functions
You define the limit values of dynamic motion characteristics at the input
parameters Velocity, Acceleration, Deceleration and Jerk.
When the dynamic value of a motion lies within the limits preset in the axis
configuration, the axis responds as follows:
Dynamic
parameters
Response when < 0 Response when = 0 Response when > 0
Velocity Use velocity preset of axis
configuration
Error: Command is ignored
Exception: MC_MoveVelocity
Use Velocity
Acceleration Use acceleration preset of
axis configuration
Error: Command is ignored
(not permitted)
Use acceleration
Deceleration Use deceleration preset of
axis configuration
Error: Command is ignored Use deceleration
Jerk Use jerk value preset of axis
configuration
Use trapezoidal profile Use jerk
A warning is output at the technology DB if the dynamic value of a motion is
outside the limits preset in the axis configuration.
Note
The preset limits of the axis configuration can be by means of FB
"MC_WriteParameter".
Note
Initially, the dynamic values in the technology function are not verified when the
motion control command starts. The command is output to the system, where the
dynamic values are verified. The system reports any errors at the corresponding
technology DB. Output parameter CommandAborted is then set at the technology
function.
