For synchronized axes:
n
The slave axis cannot be moved separately.
n
The nominal value display of the slave axis shows the nominal value of the
master axis.
n
The PLC program must ensure that the master axis does not move until the
slave axis is ready (clamping, feed-rate enable).
n
For the slave axis, the bits for traverse direction in W1030 and axis in motion
in W1028 are not set.
n
One axis cannot be both master and slave.
n
Linear and nonlinear axis error compensation as well as temperature
compensation must be entered separately for each axis.
n
The values for rapid traverse, acceleration, jerk, software limit switches,
feed rate for reference mark traverse, and manual feed rate are also taken
over from the input values of the master axis for the slave axis.
n
When operating with following error, the k
must be the same.
n
The axes must be either both analog or both digital.
n
Up to NC software 280 470-04: Master and slave axes must be linear.
n
For gantry axes, one position encoder is sufficient.
n
The nonlinear axis-error compensation can be used separately for master
and slave axes.
n
For the nonlinear axis-error compensation, master and slave axes may be
dependent on each other.
