HLP-A Series inverter have altogether 4 Ramp Times. For Ramp Time 2.3.4
the user can select the different ramp up or down time through the external
terminals or switching of ramp time according to the actual needs. In the
internal control multi-speed operation, different ramp time can be selected
through easy PLC.
Generally the default of the inverter is Ramp Time 1, which is factory set
depending on the model. Ramp Time 4 is for the jogging ramp time. For the
factory setting of parameters refer to the table in CD006.
The related parameters: CD050~CD055 and CD078.
CD020~CD030 Factory Reserved
CD031 Starting Mode
Set Range: 0—1 Unit: 1 Factory Setting: 0
Two starting modes are available for the needs of different equipment.
0: Start from the starting frequency.
When CD141 is set to 0, i.e. DC braking is invalid at start, it starts running
from the starting frequency. When CD141 is set to any non-zero value, i.e. DC
braking is valid at start, itl first performs a DC braking at start, and then starts
from the starting frequency.
For the related parameters refer to CD040, CD140 and CD141.
1: Start by frequency track
This setting can be used for the restarting of large inertia load. When
restarting, the inverter will trace the former frequency from the set frequency
downward. In case of large inertia equipment, when restarting, it can
implement the running command and track the former frequency right away
without waiting for the complete stop of the equipment to save time.
Note: When the inverter is restarted by frequency track, it will start tracking
the frequency from its set frequency downward, and search it at the highest
diagram). Ramp-down Time means the time needed for the inverter to
decrease the frequency from the maximum operating frequency to 0Hz (See
t2 in the diagram).
