Up/Down 2 Bias Step Frequency

Sets the bias that the Up/Down 2 function adds to or subtracts from the frequency reference.

0.00 Hz

(0.00 - 99.99 Hz)

The operation is different for different setting values:

  • Setting d4-03 = 0.00 Hz

    When the Up/Down 2 Command [H1-xx = 75, 76] is active, the drive uses the accel/decel times set in d4-04 [Up/Down 2 Ramp Selection] to increase or decrease the bias value.

    Figure 1. Up/Down 2 Bias when d4-03 = 0.00 Hz

  • Setting d4-03 ≠ 0.00 Hz

    When the Up/Down 2 Command [H1-xx = 75, 76] is active, the drive increases or decreases the bias in steps for the value set in d4-03. The drive uses the acceleration and deceleration times set in d4-04.
