76: Down 2 Command
Setting Function
76 Down 2 Command
If the input terminal set for the Up 2 Command is turned ON, the bias increases, and if the terminal set for the
Down 2 Command is turned ON, the bias decreases. When both commands are turned ON or OFF, the frequency
reference is held.
Note:
• When the Up2/Down2 function is used, set the optimal bias limit value using d4-08 and d4-09 [Up/Down 2 Bias Upper Limit/Lower
Limit (Up/Down 2)].
• Refer to "d4: FreqRef Hold&Up/Down Func" for details.

77: ASR Gain Switch
Setting Function
77 ASR Gain Switch
ON : C5-03
Switches the proportional gain to C5-03 [ASR Proportional Gain 2].
OFF : C5-01
Switches the proportional gain to C5-01 [ASR Proportional Gain 1].
Note:
Refer to "C5: Automatic Speed Regulator (ASR)" for details.

Polarity Inversion
ON : External torque reference reverse direction

V/f CL-V/f OLV
Decelerates the motor by reducing the frequency reference bias value when the terminal is turned
ON. Always set the Up2 command and Down 2 command as a pair.
V/f CL-V/f OLV
Switches the ASR proportional gain set in C5-01 [ASR Proportional Gain 1] and C5-03 [ASR
Proportional Gain 1/2].
V/f CL-V/f OLV
Switches the rotation direction of the external torque reference.

Operation
while the Up 2 command is turned
ON. (increases the bias value)
while the Down 2 command is
turned ON. (reduces the bias value)
following the frequency reference.
"Freq Reference + d4-03" while the
Up 2 command is turned ON. (the
bias value increases up to the value
set in d4-03)
"Freq Reference + d4-03" while the
Down 2 command is turned ON. (the
bias value reduces to the value set in
d4-03)
when the frequency reference is
changed to a value other than that set
in d4-07, the drive holds the bias
value until the output frequency and
the actual frequency reference match
(speed agreement).

Storing the frequency reference
or frequency bias
Not stored.
Not stored.
When the bias value is constant within
5 seconds after frequency reference
hold starts, the bias value being held is
stored in d4-06. Rewriting the
frequency reference is not possible.
Only the bias value is stored.
