9.2 Flying measurement (sampling)
9.2.1 Function: Flying measurement
In flying measurement, the “ac tual position” measured value c an be stored in the motor controller
through the fast sample input (DIN9)[X1.11] [X1.1.11/X1.2.11]. With the configured edge of the sample
input, the current actual position of the drive is written to the sa mple memory. A higher-order controller
can read the last stored actual position via the active fieldbus (CANopen/PROFIBUS DP/DeviceNet/
RS485). The last stored actual position is displayed in the “Project output” FCT window in the online
tab “Operation” in the dynamic data.
Activate flying meas urement via digital input
The sample input (DIN9) is only active and configurable for the control interface
“CANopen/PROFIBUS DP/DeviceNet/RS485”.
