Reduce standby power in combination with the control power supply DC24V input.
Connecting the auxiliary contact MC for the main circuit power supply to the setting terminal of the out-
put terminal function [CON] shuts off the power input to the inverter main circuit while the inverter output
is suspended to implement the operation sequence for energy saving.
The inverter waits for the output until the start waiting time passes. (1)
It turns on the contactor control signal 039[CON] at the same time.
The operation varies depending on whether the contactor check signal 107[COK] is set to the input ter-
minal function. (2)
After the start waiting time passes, there is an acceleration. (3)
After the inverter stops the output, there is a waiting time for the contactor release delay time to pass.
(4)
After the contactor release delay time passes, the contactor control signal 039[CON] is turned off. (5)
The operation varies depending on whether the contactor check signal 107[COK] is set to the input ter-
minal function. (6)
Example of Energy Saving on the Primary Side Contactor
(AF120 = 01: Enabled (Primary Side)
With [COK] setting
If the 107[COK] is not turned on during the contactor check time, the inverter trips with
the [E110] contactor error.
Without [COK] setting
After the contactor control signal 039[CON] is turned on, there is a waiting time for the
start waiting time to pass.
With [COK] setting
If the 107[COK] is not turned off during the contactor check time, the inverter trips with
the [E110] contactor error.
Without [COK] setting
The inverter still does nothing.
