Switch over parameter sets

See also in Section 9.1 under heading "Data sets"
WARNING
Parameter sets can be switched over while the converter is in operation (online). As a result,
depending on the setting of the control bits when the motor is running, the configuration or
functions may be altered in such a way as to produce dangerous operating conditions.
For this reason, we strongly recommend that a "basic" parameter set containing all basic
parameter settings is created first and then copied into the other parameter sets (using P055 or
P057) . The intentional changes vis-à-vis the "basic" version should then be entered in each
parameter set.
The "Switch over parameter sets" function affects function parameters (identified by an ".F" next to
parameter number in block diagrams in Section 8) and Bico parameters (identified by a ".B" next to
parameter number in block diagrams in Section 8).
The following operating modes are possible (see also Section 8, Sheet G181):
P649 = 9: The control bits in control word 2 are input bit-serially.
The binectors selected in P676 and P677 determine bits 0 and 1 of control word 2 (= bits
16 and 17 of complete control word), and thus the input of the function data set.
The binector selected in P690 determines bit 14 of control word 2 (= bit 30 of complete
control word), and thus the input of the Bico data set.
P649 ≠ 9:
The connector selected in P649 is used as control word 2.
Bits 0 and 1 of control word 2 (bits 16 and 17 of complete control word) control the input of
the function data set. Bit 14 (= bit 30 of complete control word) controls the input of the
Bico data set.
Caution:
When the "Switch over parameter sets" function is activated, a time delay of up to 25ms may occur
before the newly selected parameter set actually becomes operative.
For information about copying parameter sets, please see Section 11 (Parameter List), parameters
P055 and P057.
