7.7 Simulated measuring
7.7.1 General functionality
Brief description
To make measurements at real machines, probes must be connected which supply
switching signals at certain positions. Probes are not used when making measurements in
simulated environments - the switching positions are specified in a different way.
Simulated measuring supports two ways of entering switching positions:
Position-related switch request: The switching position is derived from the axial end
position programmed in the measuring block.
External switching request: The switching position is defined by controlling a digital
output.
Preconditions
For simulated measuring, all of the machine axes in the system must be parameterized as
simulated axes:
MD30130 $MA_CTRLOUT_TYPE[axis] = 0 (simulated setpoint)
MD30240 $MA_ENC_TYPE[axis] = 0 (simulated encoder)
7.7.2 Position-related switch request
Function
"Position-related switch request" is selected using the following NCK-specific machine data:
MD13230 $MN_MEAS_PROBE_SOURCE = 0
MD13231 $MN_MEAS_PROBE_OFFSET = <position offset>
The axial switching position is calculated from the axial end position programmed in the
measuring block and the parameterized position offset:
Switching position[axis] = End position[axis] - position offset
During the measuring block, it is cyclically checked as to whether the switching position of
the axis is reached:
Setpoint position[axis] ≥ switching position[axis]
When the switching position is reached, the rising edge of the switching signal is generated
for probes 1 and 2. One position controller cycle later, the following edges.
