Energy saving
Attention!
WARNING
Do not select the operation modes 11, 21 or 22, if the DC-link connection (“+” and “-”
at terminal X11) of the frequency inverter is connected to other devices.
WARNING
The operation modes to switch off the I/O’s (settings 12, 21 or 23) have the following
effects:
• The digital inputs are no longer evaluated, the last known values remain inter-
nally (i.e.
Digital inputs 250).
• The digital outputs are set to zero-
potential, internally the values are set to zero
(i.e. Digital outputs 254).
• The output X13.4 DC 10Vout is switched to zero-potential.
• The analogue inputs are further evaluated, (i.e.
Analog Input 251).
• The analogue outputs are set to zero-
potential, internally the values are set to
zero (i.e. Analog Output 257).
WARNING
For the the digital inputs (settings 12, 21 or 23) of the energy saving function “Pull-up”
(PNP-Logic) or “Pull-down” (NPN-
Logic) resistances are switched on to minimize the
internal losses. When the energy saving function is activated, the digital inputs carry up
to DC 24 V (PNP-logic) or DC 0 V (NPN-logic).
Bonfiglioli Vectron recommends not to use the settings 12, 21 and 23 for the engery saving function,
if:
• The digital input signals are used for Agile devices and third party products at the same time.
• The digital input signals on the wire are connected with Pull-down (PNP-logic) or Pull-up
(PNP-logic) resistances to Ground or DC 24 V (in example due to interference resistance).
0 - Off
The Standby mode of the frequency inverter is switched off.
Factory setting.
1 - Step1 (=Keypad+fan)
The Standby mode is switched on. The following functions are
switched off if enable is switched off:
− the display of the operator panel
1
− the internal fans
2
11 - Step1+Power unit
Standby mode is switched on. The following functions are
switched off if enable is switched off:
− the display of the operator panel
− the internal fans
− the power unit
1
This setting is independent of the setting of parameter Time until Keypad Standby 1510.
2
The internal fans will continue to run for a sufficiently long time and will be switched off then.
