2: Multi-stage frequency/revolution operation condition effective
When multifunctional input terminal (Function No.23) is valid, frequency inverter operates in multi-stage
frequency/revolution; when it is invalid, frequency inverter will automatically access to frequency setup mode
allowed to the lower priority.
3: Multi-stage PID setting operation effective
When the process PID starts its function, the setup of PID should be set automatically according to given
time cycle, at most 7 stages being set (F7.1.27 ~ F7.1.33).
4: Multi-stage PID setting operation condition effective
When multifunctional input terminal (Function No. 23) is valid, the multi-stage setting of process PID is also
valid, at most 7 stages being set (F7.1.27 ~ F7.1.33).
_ _ X _: Operation mode
0: Single cycle
Frequency inverter should firstly operate with first multi-stage speed set frequency and output each velocity's
frequency according to given operating time. If the given operating time of a certain velocity is of zero, jump
out of the velocity; With a cycle's operation, the frequency inverter should stop outputting and input an
effective operating instruction once again to run the next cycle. See as Figure 7-48-B.
1: Single cycle stop mode
The basic operation mode is the same as mode 0 and its difference is that after frequency inverter operates a
stage speed, it firstly lowers the output frequency to zero according to specified deceleration time, then
outputs next stage's frequency.
