Table 11.63 Up 2 Command, Down 2 Command
d4-05 d4-01
0 • When the Up 2 Command is active,
the drive accelerates the motor
(increases the bias value).
• When the Down 2 Command is
active, the drive decelerates the
motor (decreases the bias value)
• When the Up 2 Command and Down
2 Command are not active and when
0
the Up 2 Command and Down 2
1
Command are active, the drive holds
the output frequency (holds the bias
value).
• When the frequency changes, it will
reset the bias.
• For all other statuses, the drive will
follow the frequency reference.
• When the Up 2 Command is active,
the drive accelerates the motor.
• When the Down 2 Command is
1 - active, the drive decelerates the
motor.
• For all other statuses, the drive will
follow the frequency reference.
0 • When the Up 2 Command is active,
the drive accelerates the motor to
"Freq Reference + d4-03" (the bias
value will increase to the value set in
d4-03).
• When the Down 2 Command is
active, the drive decelerates the
motor to "Freq Reference - d4-03"
(the bias value will decrease to the
value set in d4-03).
-
• When the Up 2 Command and Down
1
2 Command are not active and when
the Up 2 Command and Down 2
Command are active, the drive holds
the output frequency (holds the bias
value).
• When the frequency changes, it will
reset the bias.
• For all other statuses, the drive will
follow the frequency reference.
0 • When the Up 2 Command is active,
the drive accelerates the motor
(increases the bias value).
• When the Down 2 Command is
active, the drive decelerates the
motor (decreases the bias value).
• When the Up 2 Command and Down
2 Command are not active and when
the Up 2 Command and Down 2
Command are active, the drive holds
0 0
the output frequency (holds the bias
1
value).
• During acceleration or deceleration,
when the frequency reference
increases or decreases more than d4-
07 [Analog Freq Ref Fluctuate
Limit], the drive holds the bias value
until the output frequency and the
actual frequency reference agree
(speed agreement).
11.8 H: Terminal Functions
Storing the Frequency Reference
Operation
Not stored.
When the bias value and frequency
reference are constant for 5 seconds
after the frequency reference hold
starts, the drive will add the bias value
to the enabled frequency reference,
then reset.
Not stored.
Not stored.
When the bias value and frequency
reference are constant for 5 seconds
after the frequency reference hold
starts, the drive will add the bias value
to the enabled frequency reference,
then reset.
Not stored.
When the bias value is constant for 5
seconds after the frequency reference
hold starts, the drive will store the bias
value in d4-06. You cannot rewrite the
frequency reference is not possible.
The drive will store only the bias
value.
