Notes:
This step assumes that you have properly set the current control and the
commutation in advance. If the current control or commutation are not
optimum, the controller tuning will yield poor results.
If you use analog sensors (Analog encoder, Resolver, Potentiometer, LVDT, etc.)
take extra care to ensure your position signals are clean before you start motion.
The sensor quality must be tested with the motor fully powered, since RFI from
the motor occasionally disturbs the sensor quality. To find the sensor quality,
open the Composer, set UM=3 (Open loop), set HT[1]=CL[1] (maximum
holding torque), and record the motion sensor Position and Speed. (The
disturbance display on the speed record is much clearer than on the position
record).
3.6.3.1 Prepare for Identification
The control tuning environment needs a working closed loop to start from. The
initial closed loop does not need high performance.
Allow the Conductor to find a controller automatically. The Conductor tries to
follow the guidelines of the Appendix on manual tuning automatically. It concludes
with a controller that has quite low performance – only enough to continue
automatic tuning from here.
On starting the Controller tool, the following window opens:
