Description
All Modes
Sets the dead-band width around each selected prohibited frequency reference
point.
Description
All Modes
0: Disabled. Drive starts from zero when the power is switched on.
1: Enabled. At power up, the drive starts the motor at the Hold frequency that
was saved.
All Modes
Sets the bias added to the frequency reference when the Up 2 and Down 2
digital inputs are enabled (H1-oo = 75, 76).
All Modes
0: Use selected accel/decel time.
1: Use accel/decel time 4 (C1-07 and C1-08).
All Modes
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.
All Modes
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.
All Modes
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.
All Modes
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.
All Modes
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.
All Modes
0: The lower limit is determined by d2-02 or an analog input.
1: The lower limit is determined by d2-02.
