0.1~3000.0s
Waiting and holding time during forward -reverse switch, after
inverter output frequency drops to zero.
Dead time of forward-reverse rotation

Dead time of forward -reverse rotation refers to the waiting and holding time of inverter. During this period of time,
inverter will transit from the current direction to the reverse direction upon receiving a reverse run command, and
its output frequency will drop to zero.
The diagram is as follows:

5.10.8 Energy-saving function V/F

In energy-saving mode, in order to minimize inverter output power in constant speed operation, inverter will
automatically control the output voltage.

Energy-saving mode

In energy-saving mode, in order to minimize inverter output power in constant speed operation, inverter will
automatically control the output voltage.
Note: 1. If selecting energy-saving operation mode, deceleration time may be longer than the set value. In addition,
compared with constant torque load , overvoltage will more likely to occur, please set the deceleration time
relatively longer.
2. For heavy-duty or frequent acceleration/ deceleration applications, energy saving effect may not be very good.
