Frequency Reference Hold
Function Selection
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.
Default: 0
Range: 0, 1

(2AA)
Frequency Reference Bias
Step (Up/Down 2)
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).
Default: 0.00 Hz
Min.: 0.00
Max.: 99.99

Frequency Reference Bias
Accel/Decel (Up/Down 2)
All Modes
0: Use selected accel/decel time.
1: Use accel/decel time 4 (C1-07 and C1-08).
Default: 0
Range: 0, 1

Frequency Reference Bias
Operation Mode Selection
(Up/Down 2)
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.
Default: 0
Range: 0, 1
66
d4-06
(2AD)
Frequency Reference Bias
(Up/Down 2)
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.
Default: 0.0%
Min.: -99.9
Max.: 100.0

d4-07
(2AE)
Analog Frequency
Reference Fluctuation Limit
(Up/Down 2)
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.
Default: 1.0%
Min.: 0.1
Max.: 100.0
67
d4-08
(2AF)
Frequency Reference Bias
Upper Limit (Up/Down 2)
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.
Default: 100.0%
Min.: 0.0
Max.: 100.0
67
d4-09
(2B0)
Frequency Reference Bias
Lower Limit (Up/Down 2)
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.
Default: 0.0%
Min.: -99.9
Max.: 0.0

Up/Down Frequency
Reference Limit Selection
All Modes
0: The lower limit is determined by d2-02 or an analog input.
1: The lower limit is determined by d2-02.
