d4: Frequency Reference Hold
Use d4 parameters to configure the drive frequency reference hold function.
d4-01
Frequency
Reference Hold
Function Selection
0: Disabled
1: Enabled
This parameter is used to hold the last frequency
reference in U1-01 (d1-01) when power is
removed. This function is available when the
multi-function inputs “accel/decel ramp hold” or
“up/down” commands are selected
(H1- = A or 10 and 11).

Reference Bias Step
(Up/Down 2)
When set to 0.00 Hz, the bias value is adjusted
according to d4-04. The final accel/decel rate is
0 (cancels Soft-Starter). When greater than 0.0
Hz, the frequency reference bias will follow d4-
03 when the Up 2 or Down 2 commands are
switched on. The acceleration or deceleration
rate is ultimately determined by d4-04.

0: Adjusts the bias value according to the
currently selected accel/decel time.
1: Adjusts the bias value by Accel/Decel Time 4

Selection
(Up/Down 2)
0: Holds the bias value when Up/Down 2
reference is on or off.
1: When the Up 2 reference and Down 2
reference are both on or both off, the frequency
reference bias becomes 0. Final reference
accelerates or decelerates at the time selected.
Enabled only when d4-03 = 0.
