EasyDrive CV3100 Series Instruction Manual page 82

CV3100 series and MINI series high performance general purpose inverter instruction manual
defined by P1.12, and then accelerate. Or the motor is controlled by the
multi-functional terminals defined as pre-excitation command to produce with
operation (provisional reservation).
1：Available all long
Execute pre-excitation to the motor when inverter starts to run. (Continued in 0.00Hz)
P1.12 Pre-excitation continuing time
Setting range
This parameter specify the duration of motor pre-excitation under vector control mode.
During motor pre-excitation, the motor is under analogous DC brake status. So in this
situation, DC brake function parameters are invalid. By adjusting the pre-excitation
function and the continuing time, it can also achieve good effect of DC brake,
P1.13 Motor auto tuning
Setting range
0：No action
1：Static tuning
If this function is selected, Press RUN key on the keypad to execute the motor
auto-tuning operation. This process is accomplished by the system automatically,
without human intervention.During this process, the other commands can not be
responded. After the auto tuning procedure is complete, P1.13 will be cleared to zero.
The parameters achieved will be stored into the inverter, namely parameter P1.05,
P1.06, P1.07 and P1.08 have been updated.
Note：This parameter is only valid under vector control mode (P0.00=0) and keypad
control mode (P0.04=0).
If over-current fault occur in the process of motor auto-tuning,please check whether
the motor current is match with the rated current of inverter. Make sure that the
inverter is in stop status before proceeding with the auto tuning,or else auto tuning will
be not done.The advantage of static tuning is to determine motor parameter under the
situation of motor shaft don't leave load.
