is not supported.
2.15 Control parameters
For closed-loop speed control, 2 parameters are provided:
P factor kp
I factor ki
Address of P factor (parameter set 1) : D10A
Address of P factor (parameter set 2) : D10B
Address of I factor (parameter set 1) : D10C
Address of I factor (parameter set 2) : D10D
Write authorisation : ebm-papst, customer, end customer
The "Internal parameter set" parameter is used to select whether the values in "P factor / I factor (parameter
set 1)" or the values in "P factor / I factor (parameter set 2)" are applicable (see 2.13 Internal parameter set).
