Machine data
2.4 Axis-specific machine data
Description: This MD defines how long the speed setpoint may be within the limit
CTRLOUT_LIMIT[n] (max. speed setpoint) until the monitoring function is trig-
gered.
Monitoring (and with it also this machine data) is always active.
Reaching the limit renders the position control loop non-linear, which
results in contour errors provided that the speed setpoint limited axis is
participating in contour generation. That is why this MD has default value 0,
i.e. the monitoring function responds as soon as the speed setpoint reaches
the limit.
Description: This MD is used to enter the encoder frequency, which,
in general, is a manufacturer specification (type plate, documentation).
For PROFIdrive:
No automatic, software-internal limitation for encoders on the PROFIdrive
drive; here, the limit values of the measuring circuit module depend on the
drive hardware used, i.e. known only by the drive. Therefore, it is the user
who is responsible for taking into account the limit frequency of the measur-
ing circuit module.
