E5 Series High Performance Universal Inverter
Pb.TT
Pb.TT
The two parameters are used to set control mode for fan and pump.
0: Basic running mode
T: Pre−overload decelerate frequency model
If this mode is selected, before overload, through real−time monitoring the load to achieve the inverter
automatically reduces the running frequency in order to ensure automatically out of overload running.
That may exist automatically reduces the running frequency when using this mode.
T: Forced energy saving mode T(square type load)
If this mode is selected, according to Pb.TT setting, the inverter automatically determines the
frequency upper limit to work in order to meet the square type load forced energy−saving rate
requirements setting in Pb.TT.
3: Forced energy saving mode T(cube type load)
If this mode is selected, according to Pb.TT setting, the inverter automatically determines the
frequency upper limit to work in order to meet the cube type load forced energy−saving rate
requirements setting in Pb.TT.
Note:
 This function is only enabled when setting P0.03 to 0
 The higher forced energy saving rate settings, the lower operating frequency upper limit of inverter
automatically determines.
Pb.T3
Parameters copy function can be realized through operation panel.
0: No operation. When upload or download is completed, the parameter is automatically restored to 0.
T: Upload parameters. Press PRG key to upload parameters to the operation panel after setting, and will
display percentage of copy process after indicating "LoAd".
T: Download parameters (without motor parameters). Press PRG key to download parameters to the
inverter, and will display percentage of copy process when indicating "CoPy". Motor parameters in
Group P9 will not be downloaded to the inverter with this operation.
3: Download parameters (all parameters). Press PRG key to download parameters to the inverter after
setting, and will prompt percentage of copy process when indicating "CoPy".
4: Upload is not allowed. The function is use to avoiding deleting parameters that have been copied to
the operation panel. After setting this function, "HoLd" will be displayed on the operation panel when
conducting parameters upload.
5: Upload is allowed, allowing uploading parameters to the operation panel after setting.
Note:
 After operation, Pb.T3 will be automatic returned to "0". ''E.CPy" will be displayed if occur copy error.
 The parameters for E5, V5 and V6 series cannot be copied each other. And the copy operation can be
performed only when the two inverters for upload and download (dT.09) are consistent.
 The copy function can be completed only when the power supply is switched off completely and
power on again.
