18
P0590 – Energy Saving Minimum Speed
Adjustable
Range:
360 to 18000 rpm Factory
Setting:
600 (525) rpm
Properties: cfg, V/f
Access groups
via HMI:
HVAC
Description:
This parameter defines the minimum speed value at which the energy saving function will remain active.
The hysteresis for the minimum speed level is of 2 Hz.
P0591 – Energy Saving Hysteresis
Adjustable
Range:
0 to 30 % Factory
Setting:
10 %
Properties: cfg, V/f
Access groups
via HMI:
HVAC
Description:
Hysteresis used to activate and deactivate the energy saving function.
If the function is active and the output current oscillates, it is necessary to increase the hysteresis value.
NOTE!
It is not possible to set those parameters, while the motor is spinning.
18.2 PROTECTION AGAINST SHORT CYCLES
The short cycle protection is intended to prevent the motor from starting and stopping in short periods of time.
In order to do so, a minimum running time and a minimum stopped time is set, inhibiting occasional run or stop
commands, except for disable general commands and/or external fault.
P0585 – Configuration of the Short Cycle Protection
Adjustable
Range:
0 = Inactive
1 = Active Factory
Setting:
0
Properties: cfg
Access groups
via HMI:
HVAC
Description:
This parameter defines if the short cycle protection is active or not on the CFW501.
