calculation based on the combination mode selection. Negative voltage and
frequency DW signal are negative signal. All other input signals of VS2 are
positive signal. If calculation result is positive, the machine forward rotates;
If the calculation result is negative, machine reverses.
2: Bipolar adjust valid, direction control invalid: In two channels combination,
it used to add or reduce frequency of another channel. It carries out signed
calculation while combination. If the result is positive, machine runs
according to[E-01] gived direction.If the result is negative, the output
frequency is "0". Bipolar signal takes part in frequency calculation, do not
change or decide the direction of the machine.
VS2 terminal input bipolar control zero hysteresis band This function
is used in the bipolar control mode to adjust the （VS2） terminal zero point
corresponding voltage range. If the zero point range is set as -1V～+1V,the
hysteresis band should be set as 1V.(only valid when it is set as "1" in ［F-48］ )
