The Up/Down 2 function setting changes the function of d4-06:
Note:
When the keypad sets the frequency reference, you do not usually use parameter d4-06.
-
When d4-01 = 0 [Freq Reference Hold Selection = Disabled] and a source other than the keypad sets the frequency reference, the drive adds the value set in d4-06 to the frequency reference. If the value set in d4-06 is a negative number, the drive will subtract it from frequency reference.
-
When d4-01 = 1 [Enabled] and a source other than the keypad sets the frequency reference, the drive will store the bias value adjusted with the Up/Down 2 command in d4-06 5 seconds after you release the Up/Down 2 command. The drive adds or subtracts the value set in d4-06 to the frequency reference.
Conditions that Reset or Disable d4-06
The drive resets and disables the bias value in these conditions:
-
d4-01 = 0 and the Run command was cleared.
-
H1-xx = 75, 76 [MFDI Function Select = Up/Down 2 Command] is not set.
-
The frequency reference source was changed.
This includes switching LOCAL/REMOTE and multi-step speed reference.
-
A digital input changed the frequency reference value.
-
d4-03 [Up/Down 2 Bias Step Frequency] = 0 and d4-05 = 1 [Up/Down 2 Bias Mode Selection = Reset when Neither / Both Closed], and the two MFDI terminals set for Up/Down 2 Command [H1-xx = 75/76] are activated or deactivated.
-
The value of E1-04 [Maximum Output Frequency] was changed.
