Determining the
acceleration
Load the machine with the maximum permissible weight.
Enter the rapid traverse rate as step height
During the step response, record the step response of the nominal velocity
value V (NOM RPM), the actual speed value V (ACT RPM), and the nominal
current value (I NOMINAL). It is permissible to limit the nominal current
value I NOMINAL during acceleration.
From the step response of the speed controller you determine the
maximum possible acceleration (incl. 10% safety margin).
a: Acceleration [m/s

Enter the maximum possible acceleration in MP1060.x.
Checking the
counting direction
On the oscilloscope, set TRIGGER to FREE RUN.
Start recording.
Change to MANUAL operating mode.
Press the axis direction buttons.
Check the counting direction on the display and if necessary, correct it with
MP210.x.
