TECHNICAL NOTE
TUNING function
Function block for MP2000 series
 
This function block sets the speed feed forward, speed loop gain, position loop gain, speed loop integral 
time constant and the position loop integral time constant in the motion setup parameter and the servo 
amplifier user constant.

• This function can be executed while in motion by another function block. But it is
possible that the motor occasionally does unexpected operation by changing the 
parameter. So it is recommended to execute this block while the motor is 
stopped. 
• To use the function block, the EXECUTE bit must be high. If the EXECUTE bit
goes low the outputs will be set to zero.
• If any of the input values are out of range, an error will occur.
• When the EXECUTE input becomes High, the speed feed forward, speed loop
gain, position loop gain, speed loop integral time constant, and position loop 
integral time constant can be set in the motion set parameter and the servo 
amplifier user constant. 
• RDA will be set after each value (FEEDFWD, SPDLOOP, POSLOOP) is set in
the servo amplifier.
