• 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 reference + 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.
