Description
V/f CL-V/f OLV CLV AOLV
Sets the function that saves the frequency reference or the frequency
bias (Up/Down 2) after a Stop command or when de-energizing the
drive.
Set H1-xx [MFDI Function Select] to one of the these values to
operate this parameter:
• A [Accel/Decel Ramp Hold]
• 10/11 [Up/Down Command]
• 75/76 [Up/Down 2 Command]
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the bias that the Up/Down 2 function adds to or subtracts from
the frequency reference.
V/f CL-V/f OLV CLV AOLV
Sets the acceleration and deceleration times for the Up/Down 2
function to apply the bias to the frequency reference.
0 : Use Selected Accel/Decel Time
1 : Use Accel/Decel Time 4
V/f CL-V/f OLV CLV AOLV
Sets the function that saves the bias value to the drive when you
open or close the two Up/Down 2 Commands [H1-xx = 75, 76]. Set
d4-03 [Up/Down 2 Bias Step Frequency] = 0.00 before you set this
parameter.
0 : Hold when Neither Up/Down Closed
1 : Reset when Neither / Both Closed
V/f CL-V/f OLV CLV AOLV
set in E1-04 is 100%.
V/f CL-V/f OLV CLV AOLV
If the frequency reference changes for more than the level set to this
parameter, then the bias value will be held. Parameter E1-04
[Maximum Output Frequency] is 100%.
V/f CL-V/f OLV CLV AOLV
Sets the upper limit of the Up/Down 2 bias as a percentage of E1-04
[Maximum Output Frequency].
V/f CL-V/f OLV CLV AOLV
Sets the lower limit of the Up/Down 2 bias as a percentage of E1-04
[Maximum Output Frequency].
V/f CL-V/f OLV CLV AOLV
0 : Greater of d2-02 or Analog
1 : d2-02
V/f CL-V/f OLV CLV AOLV
Sets the function that changes the frequency reference to a Bi-
Directional internal frequency reference.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the gain to adjust the stopping accuracy. Set this parameter
when b1-03 = 9 [Stopping Method Selection = Stop with Constant
Distance].
