In order to do this, the frequency changer must be configured so that an output signal of 0 V at the controller's
analogue output corresponds to the minimum frequency and an output signal of 10 V to the maximum
frequency. The input signal of the frequency converter must be configured as 0 V - 10 V interface.
Operating mode combined control with capacity-controlled fixed-speed compressors (parameter
M.com.out.reg. = Yes)
With compressor combined control of capacity-controlled fixed-speed compressors, a single-stage speed
controlled compressor is combined with one or more capacity-controlled fixed-speed compressors.
In the case of the combination of a single-stage speed-controlled compressor with capacity-controlled, i.e.
multi-stage fixed-speed compressors, the sudden power variation when loading / unloading a fixed-speed
compressor capacity stage is lower than when a complete compressor would be loaded / unloaded.
The simplified diagram below shows an example of the connection of a system with one single-stage FC
compressor in combination with three two-stage fixed-speed compressors:
