If the rated motor current is less than or equal to 80% of the rated Inverter current, the base
value is the rated motor current.
•
If the rated motor current is greater than 80% of the rated Inverter current, the base value is
80% of the rated Inverter current.

Linear acceleration/deceleration.
The output frequency increases or decreases in linear mode. The DLB1 provides four group of
acceleration/deceleration time, which can be selected by using P4.00 to P4.08.
•
1: S-curve acceleration/deceleration A
The output frequency increases or decreases along the S curve. This mode is generally used in
the applications where start and stop processes are relatively smooth, such as elevator and conveyor
belt. P6.08 and P6.09 respectively define the time proportions of the start segment and the end
segment.
•
2: S-curve acceleration/deceleration B
In this curve, the rated motor frequency f is always the inflexion point. This mode is
usually used in applications where acceleration/deceleration is required at the speed higher than
the rated frequency.
When the set frequency is higher than the rated frequency, the acceleration/ deceleration time is:
t = (
