Couplings
The following coupling types can be used:
● Master value (setpoint, actual value, simulated master value)
● Coupled motion
● Tangential correction
● Electronic gear (ELG)
● Synchronous spindle
Configuration of leading axis NCU
The lead link axis that is being interpolated as a leading axis on the NCU is configured on
the interpolating NCU as a standard local axis. It is configured by means of channel axis and
machine axis machine data, and via the logical machine axis image. In addition, there are
the following requirements:
● The machine axis must be identified as lead link axis in machine data:
● Number of link module:
● Activation of link functionality:
● Number of link modules:
● Size of servo buffer specified in:
Configuration of following axis NCU
In addition to configuring the standard channel/machine axis machine data, you need to
configure machine axis machine data on the NCU that is deriving following axis movements
from the non-local leading axis (lead link axis):
● Number of link module:
● Activation of link functionality:
● Number of link modules:
● Possibly MD18402 $MN_MM_NUM_CURVE_SEGMENTS
● Possibly MD18404 $MN_MM_NUM_OF_CURVE_POLYNOMS
● Size of servo buffer specified in:
