0 • The drive accelerates the motor
while the Up 2 command is turned
ON. (increases the bias value)
• The drive decelerates the motor
while the Down 2 command is
turned ON. (reduces the bias value)
• When the Up 2 command or Down 2
0 command are not inputted, or when
1
both commands are enabled, the
drive holds the output frequency.
(holds the bias value)
• Resets the bias if the frequency
changes.
• In any other state, the drive operates
following the frequency reference.
• The drive accelerates the motor
while the Up command 2 is turned
ON.
• The drive decelerates the motor
1 -
while the Down command 2 is
turned ON.
• In any other state, the drive operates
following the frequency reference.
0 • The drive accelerates the motor up to
"Freq Reference + d4-03" while the
Up 2 command is turned ON. (the
bias value increases up to the value
set in d4-03)
• If the Down2 command is enabled,
the drive decelerates the motor to
"Freq Reference - d4-03." (the bias
value reduces to the value set in d4-
03)

• When the Up 2 command or Down 2
command are not inputted, or when

drive holds the output frequency
1
(holds the bias value)
• During acceleration or deceleration,
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).
11.8 H: Terminal Functions
Storing the frequency reference
Operation
Not stored.
When the bias value and frequency
reference are constant within 5 seconds
after frequency reference hold starts,
the bias value will be added to the
enabled frequency reference and then it
will be reset.
Not stored.
Not stored.
When the bias value and frequency
reference are constant within 5 seconds
after frequency reference hold starts,
the bias value will be added to the
enabled frequency reference and then it
will be reset.
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.
