Speed controller  Position the axis or spindle to be optimized at a location where it can be
commissioned safely.
 Set MP1340.x = 0 to deselect evaluation of the reference marks.
 Ensure that the loaded PLC program fulfills the following conditions:
 Position control loop is opened, because the NC opens the position control
loop only during the step function. If the position controller is not optimized,
error messages appear if the position control loop is closed.
 Enable the drive controller
 NC stop inactive
 Axis direction buttons active
 Axes clamped
 In the Programming and Editing mode of operation, use the MOD key to
enter the code number 688379 to switch to the Drive Diagnostics mode
of operation.
 Press the OSCI soft key.
 Set the following values in the Oscilloscope:
Output: Step
Feed rate: 100
Channel 1: I nominal
Trigger: Free run
 Press the OSCI soft key to switch the curve representation.
 Press the START soft key to start recording.
 Set the feed-rate override potentiometer to 100%.
 Commission the speed controller with TNCopt.
Feedforward  Position the axes to a location where the feedforward functions can be
commissioned safely.
 Set the datum for the affected axes at this location to "0".
 In MP1060.x, set the acceleration to 0.5.
 In the Program Run, Full Sequence mode of operation, select the NC
program FF_*.H (* = axis to be optimized) from the TNC:\TNCOPT folder.
 Set the feed-rate override potentiometer to 100%.
 Commission the feedforward functions with TNCopt.
Note
TNCopt generates the NC programs FF_*.H with the feed-rate values 6000
and 200. The larger feed-rate value should equal the machine’s highest
machining feed rate. Adjust them if necessary. The lower feed-rate value
must not be changed.
