Energy saving
The quadratic characteristic follows the function: |U| ~ f
2
.
After switching over to the quadratic characteristic, the characteristic is defined by the following pa-
rameters:
−
Starting Voltage 600
−
Voltage Rise 601
−
Rise Frequency 602
−
Cut-Off Voltage 603
−
Cut-Off Frequency 604
The parameters must be adjusted to the application. Additionally, check the settings for
Starting Cur-
rent
623 and Frequency Limit 624.
The parameters are described in chapters 7.7 "V/f characteristic" and 7.3.2 "Starting behavior".
The working range is between
Minimum Frequency 418 and Maximum Frequency 419.
8.3 Standby mode
Standby reduces the power consumption of the frequency inverter. The consumption is reduced and
energy is saved.
1510 Time until Keypad Standby
The display of the operator panel is switched off if no button is pressed within the time set in parame-
ter
Time until Keypad Standby 1510. Standby mode of the operator panel is indicated by a spot light-
ing up on the operator panel.
Standby mode is cancelled automatically is a warning or an error is signaled.
Standby mode of the operator panel is switched off if
Time until Keypad Standby 1510 is set to zero.
In this case, the display is switched on permanently.
1510 Time until Keypad Standby 0 Min 60 Min 0 Min
If the display of the operator panel is to be switched off as soon as enable of the fre-
quency inverter is switched off
– and not after a certain time –parameter
1511 can be set.
1511 Standby Mode (frequency inverter)
The frequency inverter reduces power consumption if
− the standby mode of the frequency inverter is switched on via parameter
Standby Mode 1511,
and
− enable of the frequency inverter via digital inputs STOA and STOB is switched off
