PARAMETER DESCRIPTION 266
Frequency acceleration time of V/F complete separation indicates the time accelerates from 0 to base frequency
(01-06(P.7)).Frequency deceleration time indicates the time decelerates from base frequency to 0 (01-07(P.8));
voltage acceleration time of VF complete separation indicates the time accelerates from 0 to the rated motor
voltage t1 (10-42(P.702)). Voltage deceleration time of VF complete separation indicates the time decelerates from
the rated motor voltage to 0 t2 (10-43(P.703)).

Use 10-41(P.701) to set digital voltage, the setting value cannot exceed motor rated voltage.
When voltage acceleration time is less than frequency acceleration time or voltage deceleration time is more than
frequency deceleration time, voltage stall or current stall may occur during acceleration/ deceleration, which leads
to alarm. So it is suggested that 10-42(P.702)＞ 01-06(P.7) and 10-43(P.703) ＜ 01-07
(P.8)

5.11.14 Regeneration avoid function
When inverter load inertia is larger, during deceleration or other process PN voltage will increase due to regenerative
power, and OV alarm will occur. This function can keep PN voltage fixed and prevent PN level from increasing to
OV level by adjusting inverter output frequency and voltage.
