which speed setpoint for the FC compressor is output following the loading / unloading of a compressor
capacity stage.
M.com.out.reg . = YES
This is used to specify that the stages of the fixed-speed compressors are switched on individually when
using compressor combined control (capacity control of the fixed-speed compressors is active). NO in this
case means that the fixed-speed compressors together with their capacity stages are always loaded and
unloaded completely (capacity control of the fixed-speed compressors is inactive).
MaxFreq.FC[Hz] = 87
The frequency to be output by the FC for 10 V correcting variable is set here (setting value must correspond
to the value set on the FC; the example here uses 87 Hz).
MinFreq.FC[Hz] = 30
The frequency to be output by the FC for 0 V correcting variable is set here (setting value must correspond
to the value set on the FC; the example here uses 30 Hz).
U.WorkFreq[Hz] = 67
Upper operating frequency: The maximum FC speed output by the controller is set here. This must be
selected to be less than or equal to the maximum frequency to be output by the FC.
L.WorkFreq[Hz] = 35
Lower operating frequency: The minimum FC speed output by the controller is set here. This must be
selected to be greater than or equal to the minimum frequency to be output by the FC.
The parameter Min. speed % has no function for this operating mode
The following settings must be made under 3 Setpoints / 6 Base Load for the above named example system:
BaseLoadRot.FC = N In the case of a configuration with an FC compressor with integrated FC, the frequency
converter cannot be switched. The base load rotation according to the above time interval is only performed for
the fixed-speed compressors.
5.4.3.3 Neutral Zone with Compressor Combined Control
Definition
If the control variable (t
0
) is within the range of the neutral zone, no changes are performed by the controller.
The regulation setpoint is always in the middle of the neutral zone.
The compressor combined control shows the following behaviour in the neutral zone:
No fixed line compressor switching operations are performed
The input signal for the frequency-controlled compressor continues to be calculated
The loading and unloading times for fixed-speed compressors are not started
The neutral zone can be configured separately for day and night operation.
