8.5.2 Configuring speed parameters
Fill in the following fields:
•
PID (
proportional
–integral–derivative)
control parameters
: Only experienced and qualified
person should adjust these parameters (see also section
o
Kp:
Proportional amplification in the speed controller.
o
Ti:
Integration time for the speed controller.
o
Td:
Differential time constant for the rate time in the speed controller.
o
TiM:
Maximum value of the speed integral memory.
o
Kacc:
Dynamic acceleration value directly to the current controller. There is a risk of current
oscillations if this parameter is adjusted too high.
o
Filter:
Low-pass filtering of the feedback input to the speed control. Used to decrease the
variation of the speed in order to keep it stable.

Application speed definitions
The purpose of acceleration and deceleration ramps is to lower the load on the motor and turbine
during start and stop of pitch operation.
