Parameterizing the actual value acquisition / mechanical system

The actual value acquisition / mechanical system can only be parameterized for the
Extended Functions.
For parameterization of the actual value acquisition, only the parameters required for your
configuration are offered:
Axis type
Select the "Linear axis" or "Rotary axis / spindle" axis type.
Topology
Select whether you are using a "1-encoder system" or a "2-
encoder system."
Modulo range - only for rotary axis / spindle
Set the modulo value in degrees for rotary axes for the "Safe
Position" function here. This modulo value is taken into ac-
count for safe homing and for the transfer of the safe position
via PROFIsafe when absolute position is enabled.
The safety functions are executed in the sampling time dis-
played in the "Monitoring cycle".
The actual value acquisition cycle defines the cycle time in
which the actual values for Safety Integrated are acquired.
A slower cycle time reduces the maximum permissible
•
velocity, but also reduces the load on the Control Unit for
safe actual value acquisition.
The maximum permissible velocity which, if overshot, can
•
trigger faults in the safe actual value acquisition, is dis-
played in r9730.
Setting criteria if the motion monitoring functions are execut-
ed without an encoder:
The actual value acquisition cycle must be set the same
•
as the current controller cycle (p0115).
The "Accept encoder data" button is available online and
allows you to update the safety parameters.
Depending on whether the configuration is a 1-encoder or 2-
encoder system, the appropriate encoder parameters are
copied from the basic system to the corresponding safety
parameters.
Direction of rotation reversal
Here, you can set whether a direction of rotation reversal is
involved for the particular gearbox.
