The initial value of the sampling time is specified by the RT0 cycle time Z1.8– (or by the
accordant value from the PWM frequency Z130.15– (or from the PWM frequency in the
stored system information).
Via the demands to the phase reserve and the amplitude margin Kp and Tn of the speed
controller are calculated; this way the controllers gains can be set higher or lower (Td of
the speed controller is set to zero, always).
After this and due to the bandwidth of the closed speed closed loop the gain Kv of the
position controller is submitted.
Step 4: Show result
Here the result of the frequency analysis can be checked from different points of view be-
fore transmitting the evaluated and optimized values to the final parameters.
Step 5: Download optimized values
Here the evaluated and optimized values can be transmitted to the controller.
NOTE!
At this point ProDrive allows, to freely define or change the sampling time as well the
current time constant in order to optimize the controller and Isq-set-polynomial filter.
With a change of these variables the result of this optimization does not accord to the
current system or the system from which the stored system information originates.
The user must check the parameters
Z1.8– and Z130.15– and set them again, if re-
quired.
NOTE!
ProDrive transfers the optimized values to the coefficients of the Isq-set-polynomial
filter, but doesn’t activate the filter automatically. The user must control the state of
the filter (
Z29.2–) and activate the filter (Z29.1–), if necessary.
