Up/Down 2 Command with Frequency Reference from Input Sources Other Than the Keypad
When a Run command is active and you release the Up/Down 2 command for longer than 5 s, the drive will save
the bias value in
d4-06 [Frequency Ref Bias (Up/Down 2)]
. The drive saves the frequency ref
d4-06
as a
frequency reference value. The drive will use the new value as the frequency reference when it restarts.
Figure 2.65 Up/Down 2 Example with Other Reference than Keypad and d4-01 = 1
Note:
To use the combination of the frequency reference hold function and the Up/Down 2 function, configure the Up/Down 2 upper limit
[d4-08]
and lower limit
[d4-09]
correctly.
Remove the Saved Frequency Reference Value
The procedure to remove the saved frequency reference value is different for different functions. Use these methods
to remove the value:
•
Release the input programmed for
Accel/Decel Ramp Hold [H1-xx = A]
.
•
Set an Up or Down command while no Run command is active.
•
Use the Up/Down 2 Command to set
d4-06 = 0.0
or set
d4-06 = 0.0
during stop.
