An error reaction is triggered when the limit velocity is exceeded (F7059)
Data reference
The data reference of position, velocity, acceleration and torque/force specifies
whether the data refer to the motor shaft or to the load.
The data reference (motor shaft or load) has to be the same for SMO scaling
types position, velocity and acceleration.
With percentage-based scaling in the functional part and absolute scaling in
SafeMotion for torque/force, the data reference also has to be the same.
The scaling defines in which format (unit) the data are displayed. Not all setting
variants for scaling and data reference are supported. The setting of the data
reference is restricted by the encoder used and its mounting position, as well
as the desired data representation:

When the limit velocity is exceeded, the velocity feed-
WARNING
back value (P-0-3258) and the position feedback value
(P-0-3257) are incorrectly calculated. The position is
already generated incorrectly the first time the limit
velocity is exceeded!
Check whether the limit velocity is exceeded in your
application:
−
The limit velocity cannot be reached due to the
mechanical design (motor speed, gearbox, ...):
→ There is no need for action
−
The limit velocity can be reached, but is not used in
the application:
−
The safety function "Safe maximum speed" (SMS)
is not active:
→
"Safe maximum speed" (SMS) and set the
Safe maximum speed (P-0-3270.0.2) to the limit
velocity.
−
The safety function "Safe maximum speed" (SMS)
is already active:
→ Compare the limit of the safe maximum speed
currently set (P-0-3270.0.2) to the limit velocity
and, if necessary, reduce the safe maximum
speed.
−
The limit velocity is exceeded by the application:
→ Increase the limit velocity by increasing the
overflow
P−0−3221.0.6 from 360° to 720°, for example.
