This mask permits to select the compressor model controlled by Power+.
Every change must be followed by the “Set defaults” command to send the new
parameters values to the Power +.
For specific particular purpose, it is possible to save as “Custom” a special configuration
made by changing some parameter of the characteristic ones of a compressor model.
N.B.: the modification of the Power+ parameters has to be done by qualified personnel
only, because it can result in a damage either for the compressor than for the Power+.
This masks allows to set the delay time before giving the alarm “Power+ offline” due to
the absence of answers to the enquire of the ; the last row parameter permits
to overcome ghost alarms at power up, e.g. when the “Safety Torque Off” digital input of
the Power+ is used.
This mask permits to select the measuring unit of the speed shown in the mask “Sn11”
6.2.2.1.4Pb Menu: Power+ regulation
Reserved to Power + inverter regulation: there is no need to access to these masks for the purpose of this application
program as all necessary setting has already been configured at the origin.
The parameters show the frequency limits of Power+ referred to the selected
compressor.
It may be necessary to avoid particular frequencies in some systems due to mechanical
resonance problems. Using the following parameters it is possible to fix the limits of the
frequency area to be avoided for the frequency set point.
Switching frequency and its optional setting.
This masks defines the stopping mode with no deceleration ramp control, the disabling of
the reverse speed (compressor damage!) and of the flying start (not possible with
compressor).
The parameters of this mask permit the configuration of the output relay and of the PTC
reading input (not used) with the relevant alarm delay time.
6.2.2.1.5Pc Menu: Power+ custom
Reserved to Power + inverter regulation: there is no need to access to these masks for the purpose of this application
