Parameters
Electronic axis clamping on axis
halt
Only single axis movement via
jog buttons
Maximum machine speed for
linear movements
Maximum machine speed for
radial movements
Velocity feedforward control for
position feedback control
Function of the velocity feedforward control
The velocity feedforward control influences the command action of the position-
controlled drive. It directly affects the speed control loop as a control factor and
can reduce the following error without compromising the stability of the control
loop.
If you configure the Velocity feedforward control for position feedback control
parameter, the velocity feedforward control calculates the following error that
would result due to the current speed in the position controller and, starting from
this, determines a nominal speed value that is added to the output of the position
controller.

Explanation
Setting for electronic axis clamping when the axis is at a stand-
still
Settings:
ON: The axis is clamped on standstill of the axis
OFF: The axis is not clamped on standstill of the axis
Default value: OFF
Definition of the axis movements that are possible with the
traverse keys
Settings:
ON: Only a single axis can be moved
OFF: Several axes can be moved simultaneously
Default value: OFF
Definition of the maximum speed at which NC-controlled linear
axes can be moved
Setting range: 100 mm/min ... 10000 mm/min
Default value: 2000
The Maximum machine speed cannot be exceeded,
even if you have defined a higher feed rate for
individual axes.
Definition of the maximum speed at which NC-controlled
rotational axes can be moved.
Setting range: 72000 °/min ... 3600000 °/min
Default value: 720000
Setting the Velocity feedforward control for position feedback
control of interpolated NC movements. Reducing the following
error directly affects the speed control loop
Settings:
None
t - 2 ms
t - 4 ms
