SIMOREG DC Master Operating Instructions
9.10 Switch on auxiliaries
The function acts as a switch-on command for auxiliaries (e.g. motor fan).
The "Switch on auxiliaries" signal is available at binector B0251:
log. "0" state = Auxiliaries OFF
log. "1" state = Auxiliaries ON
To act as the auxiliaries drive signal, this binector must be "wired up" to a binary output, e.g. by setting
P771 to 251 for connection to output terminals 46 / 47 (see Section 8, Sheet G112, for other possible
settings).
The "Switch on auxiliaries" signal switches to "high" at the same time as the "Switch on" command.
The converter then waits in operating state o6.0 for a parameterizable delay period (P093). The line
contactor is closed on expiry of the delay.
When the "Shutdown" command is entered, the firing pulses are disabled when n < n
min
is reached
and the line contactor drops out. The "Switch on auxiliaries" signal switches to "low" after a
parameterizable delay period (P094). However, if the "Switch on" command is entered again before
this delay has expired, then the converter does not stay in operating state o6.0, but the line contactor
is closed immediately instead.
9.11 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. The
intentional changes of 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.
