·
Even though the auto energy saving mode is set, normal control actions will be used during the acceleration/deceleration.
·
Different from the stopping actions in simple energy saving, since this function enters the deceleration together with
stopping command, the stopping time equals to the time of normal stopping actions. However, when the regenerated energy
cannot be used fully and a torque limiter is required, the deceleration time will be prolonged according to the protective
function.
·
Auto energy saving control is effective during constant-torque operation. When rated speed has been exceeded during
constant-power operation, a weak magnetic control will be adopted as normal modes.
·
The function of auto energy saving is more obvious under light loads.

V•f separation function is based on V/f control mode, it can separately control the output frequency and output voltage of the switcher.
A complete separation and proportional separation can be selected by the function codes.

2) Input method of frequency & voltage command
The frequency command (F1002) is selected according to speed 1, the setting can be made on the operation panel and from
external.
Note: If frequency command F1002 is iteratively set with VIF1 external analog, it will conflict with the output voltage
command during V•f separation. Therefore, the iterative setting of the VIF1 terminal should be avoided.
The output voltage command can input the DC voltage (0~10V) into the external control terminals "VIF1" and "ACM1" or
"ACM2" on the inverter and input voltage into "VIF1" from internal power supply "+V" and external potentiometer. For
the external potentiometer, please refer to the connection and correct installation of control circuit terminals.
(Parameters of external potentiometer: resistance =5kΩ, capacity=over 0.3W.)
The output voltage command can input the 0~10V voltage into VIF1 and set the V•f separation command voltage:
correspond to VIF1 command voltage in F2002. When the command voltage is set by function code, please set the V/f
separation command voltage: F2002≠0.
3) Gain of output voltage command
① V•f proportional separation (F1001=40 & F2001=1)
In normal V/f pattern, the voltage command Vin for current frequency is gained through the external control terminal
"VIF1" inputs (0~10V), and the output voltage command is sent to the inverter. There is a proportion between the
frequency command and the voltage command. However, the proportion is changed with the changes of VIF1 inputs.
The relationships between VIF1 voltage input and gain coefficient are as follows:
Gain coefficient
VIF1=0V input,
=5 V input,
=10 V input,
Vin= Current voltage command
