5 Parameter
BU 0600 en-3221 149
P464 Fixed frequency mode S
Setting range 0 … 1
Factory setting { 0 }
Description This parameter determines the form in which fixed frequencies are to be processed.
Note The highest active fixed frequency is added to the setpoint value of the motor
potentiometer if functions 71 or 72 are selected for two digital inputs.
Setting values
Value Meaning
0 Add to main setvalue Fixed frequencies and the fixed frequency array are added to each
other. That means, they are added together, or added to an
analogue setpoint to which limits are assigned according to
P104
and P105 .
1 Equal main setvalue Fixed frequencies are not added - neither together, nor to main
analogue setpoints.
If for example, a fixed frequency is switched to an existing
analogue setpoint, the analogue setpoint will no longer be
considered.
Programmed frequency addition or subtraction to one of the
analogue inputs or bus setpoints is still possible and valid, as is the
addition to the setpoint of a motor potentiometer function (function
of digital inputs: 71/72).
If several fixed frequencies are selected simultaneously, the
frequency with the highest value has priority (example:
20 > 10 or
20 > -30).
P465 Fixed freq. Array
Setting range -400.0 … 400.0 Hz
Arrays [-01] = Fixed frequency array 1
[-02] = Fixed frequency array 2
…
[-31] = Fixed frequency array 31
Factory setting { 0.0 }
Description In the array levels, up to 31 different fixed frequencies can be set, which in turn can be
encoded for the functions 50… 54 in binary code for the digital inputs.
P466 Minimum freq. proc. control S P
Setting range 0.0 … 400.0 Hz
Factory setting { 0.0 }
Description "
Minimum freq. proc. control
". With the aid of the minimum process controller
frequency the control ratio can also be kept to a minimum ratio, even with a master
value of “zero”, in order to enable adjustment of the compensator. Further details can
be found in
P400 and (Chap. 8.2 "Process controller").
