4.2.27 Calculate speed controller parameters

This function extension is available from software version V5.0 onwards!

The device command C00002

= "78: Calculate speed controller parameters" is used to calculate the

gain, reset time, and rate time of the speed controller.

Precondition:

The moments of inertia for the motor (C00273/1) and load (C00273/2) have been

parameterised correctly before.

• The calculation is carried out according to the following formulas, taking the actual speed value

filter time constant into consideration (C00497

):

• After the device command has been executed successfully (see status in C00003

), the calculated

values are set in the corresponding codes:

• C00070

: Speed controller gain

• C00071

: Speed controller reset time

• C00072

: Speed controller rate time

• In the event of an error, these codes are not altered.
