Analog speed command of rotation upper and lower limit setting
The function is to set external input analog at analog speed mode. Users can set a pair of volage in the range of
-10V~+10V by parameters Po433, Po431 as upper and lower limit of the analog input voltage.After analog input
is determined,analog speed can be set via parameter Po432, Po430, lower bound corresponds to the voltage on the
analog control speed.
Analog upper and lower limit setting
value is related to the accuracy of the analog
voltage control,the wider the range of upper
and lower limits is,the higher the voltage
accuracy is. Do not set the range of upper
and lower limit values too small in order to
avoid influence on effect of analog
adjustment. Specific relationship is shown in
the figure on the right:

Note: in analog speed mode, the motor speed calculation formula is as below:
Corresponding speed of lower limit voltage=value of Po400 X value of Po430
Corresponding speed of upper limit voltage=value of Po400 X value of Po432
