Description
V/f CL-V/f OLV CLV AOLV
Determines whether the frequency reference or the frequency bias
(Up/Down 2) value is saved when the Stop command is entered or
the power supply is shut down.
This parameter is effective when H1-xx [MFDI Function Select] has
been set to one of the following.
• H1-xx = A [Accel/Decel Ramp Hold]
• H1-xx = 10/11 [Up/Down Command]
• H1-xx = 75/76 [Up/Down 2 Command]
The Frequency Reference Hold function depends on which function
it is combined with.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the bias added to or subtracted from the frequency reference by
the Up/Down 2 function.
V/f CL-V/f OLV CLV AOLV
Selects the acceleration and deceleration times to use when adding
or subtracting the bias to/from the frequency reference when using
the Up/Down 2 function.
0 : Use selected Accel/Decel time
1 : Use Accel/Decel Time 4
V/f CL-V/f OLV CLV AOLV
Determines if the bias value is saved to the drive when Up/Down 2
Command [H1-xx = 75, 76] are both released or both enabled. This
parameter is effective only when d4-03 [Up/Down 2 Bias Level] =
0.00.
0 : Hold bias @ no Up/Down selected
1 : 0 bias @ neither/both selected
V/f CL-V/f OLV CLV AOLV
E1-04 [Maximum Output Frequency] 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
Down function.
0 : d2-02 or Analog (larger level)
1 : d2-02
