feedback and PID setting is smaller than the value of P6.19, group 1 is selected. When the
absolute value of the deviation between PID feedback and PID setting is higher than the
value of P6.20, group 2 is selected. When the deviation is between P6.19 and P6.20, the
PID parameters are the linear interpolated value of the two groups of parameter values.

When the AC drive starts up, the PID starts closed-loop algorithm
only after the PID output is fixed to the PID initial value (P6.21)
and lasts the time set in P6.23, see figure 6-28.
