decel times are used for acceleration or deceleration.
The Up/Down 2 bias value is saved in d4-06 when the frequency
Up/Dn 2 Bias Lvl reference is not input by the digital operator. Set as a percentage
of the maximum output frequency.
Limits how much the frequency reference is allowed to change
while an input terminal set for Up 2 or Down 2 is enabled. If the
frequency reference changes for more than the set value, then

the bias value is held and the drive accelerates or decelerates to
the frequency reference. Set as a percentage of the maximum
output frequency.
Sets the upper limit for the bias and the value that can be saved
in d4-06. Set as a percentage of the maximum output frequency.
Up/Dn 2 UpperLim
Sets the lower limit for the bias and the value that can be saved
in d4-06. Set as a percentage of the maximum output frequency.
Up/Dn 2 LowerLim
Up/Dn LowLim Sel 0: The lower limit is determined by d2-02 or an analog input.
0: D2-02 or Analog 1: The lower limit is determined by d2-02.

Description
The functionality of setting 1 is only accessible
via MEMOBUS/Modbus communication.
