Starting/stopping the measuring function
!
Caution
With the corresponding measuring function parameter settings (e.g. offset), the
motor can “drift” and travel to its end stop.
The movement of the drive is not monitored while the measuring function is active.
To start the ramp-function generator:
1. Meet the conditions for starting the measuring function
– Activate the control board
Drives -> Drive_x -> Commissioning -> Control board
– Switch on the drive
Control board -> Issue enable signals -> Switch on
2. Select the drive (as control board)
3. Set the measuring function
e.g. current controller setpoint change
4. Load the settings to the target system (“Download parameters” pushbutton)
5. Start the measuring function (“Start Measuring Function” pushbutton)
To stop the measuring function:
“Stop Measuring Function” pushbutton
