The maximum speed is the limitation for the speed of all motion functions with a ramp (profile velocity
mode, profile position mode). I.e. the speed cannot become greater than this value, even if a different
parameter (e.g. Target velocity 60FFh) contains a higher value.
In the mode of operation “Velocity controller with analogue input”, this value corresponds to the
maximum achievable speed (-10 V …-+10 V relate to –max. velocity ... +max. velocity). See “Mode of
Operation dialogue box” on page 54.
The determination of this parameter can be carried out automatically. Here, it is, however, necessary
to define a motion sector, since the axis might cover a long way during the acceleration to the
maximum speed and the subsequent braking and may not drive into the mechanical stop.
See “Acceleration dialogue box“ on page 67.
In order to determine this motion area, at least one limit point has to be set in which the axis is driven
to the corresponding spot via a Teach dialogue. In the beginning, both limit points contain the actual
position.
The acceleration is by default set to 20 % of the maximum acceleration in order to go easy on the
mechanical parts, if e.g. the motion sector becomes too small.
