CV3100 series and MINI series high performance general purpose inverter instruction manual
f1～f7：Running frequency corresponding from Stage 1 to 7;
T1～T7：Running time corresponding from Stage 1 to 7;
a1～a6：Acceleration time corresponding from Stage 1 to 7;
d3、d5 & d7： Deceleration time for stag 3、stage 5 and stage7.
Note：
Multi-step speed running time must be longer than acceleration time, however, this
parameter only defines the running time, so it is necessary to learn the calculation of
multi-step speed running acceleration/deceleration time, shown as following:
Multi-step speed acceleration/deceleration time=｛（Current multi-step speed
frequency- multi-step speed starting frequency）÷ Basic running frequency｝×
Acceleration & Deceleration time (P0.14, P0.15)
For example, if basic running frequency is 50Hz，acceleration time is 10S，and
deceleration time is 20S，during multi-step speed running, the accelerating time for
inverter increasing from 20HZ to 30HZ as below:
T1=｛（30HZ-20HZ）÷ 50HZ｝× P0.14=2S
Decreasing from 30HZ to 10HZ, the decelerating time as below:
T2=｛（30HZ-10HZ）÷ 50HZ｝× P0.15=8S
2：Continuous circulation
When the stop command is input, the continuous circulation will be ceased, shown as

3：Holding ultimate value after single circulation
As is shown in Diagram 6-28, the inverter finishes multi-step speed single circulation,
then it will keep the running frequency and direction of last section, of which running
time is not set to ―0‖.
