YASKAWA SIEP YAIP1U 01C AC Drive - P1000 Technical Manual
Description
0: Bias value is held if no input Up 2 or Down 2 is active.
1: When the Up 2 reference and Down 2 reference are both on or both off, the
applied bias becomes 0. The specified accel/decel times are used for
acceleration or deceleration.
The Up/Down 2 bias value is saved in d4-06 when the frequency 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.
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.
0: The lower limit is determined by d2-02 or an analog input.
1: The lower limit is determined by d2-02.
Description
Sets the drive output voltage for the Field Weakening function as a percentage
of the maximum output voltage.
Enabled when a multi-function input is set for Field Weakening (H1-oo =
63).
Sets the lower limit of the frequency range where Field Weakening control is
valid.
The Field Weakening command is valid only at frequencies above this setting
and only when the output frequency matches the frequency reference (speed
agree).
