8. Further increase proportional gain of the speed controller in 0x2900:1
(or 0x3100:1 for B)
until the speed control loop starts to be unstable again.
• If the oscillation frequency has changed now, readjust the filter frequency by trimming.
The use of a second filter is ineffective here.
• If the oscillation frequency remains the same, readjust the filter depth and/or the filter
width by trimming (the first reduces the amplitude, the second lets the phase rotate
faster).
• Repeat step 8 until the desired behaviour or the limit of a sensible speed controller gain
has been reached.
9. Check the drive behaviour in case of quick stop (QSP)
• Accelerate drive
• Then, brake with quick stop (QSP) and check whether a reduced drive dynamics can be
detected.
• If so, reduce the influence of the filters until the reachable dynamics corresponds to the
requirements.

For permanent storage, the changed settings must be uploaded to the controller from
the i700 servo inverter.
The »EASY Starter« serves to save the parameter settings of the i700 servo inverter as
parameter file (*.gdc). In the »PLC Designer«, this file can then be imported in the
corresponding axis. Saving changed parameters safe against mains failure
