combination of DI terminal correspond to the different set frequency value. PI9000 can set up
more than 4 multi-stage command terminals and 16 statuses, and any 16 "multi-stage
commands "can be achieved correspondence through E1 group function code, the "multi-
stage command" refers to the percent of F0.19 relative to maximum frequency.
Under the mode, DI terminal function in F1 group parameters will be required to set as
the multi-stage command.
7: Simple PLC program setting
Under the mode, the inverter operating frequency source can be switched between 1 to
16 any frequency commands, the user can set hold time and ac/deceleration time for 1 to
16 frequency command , the specific content refers to the related E1 group instructions.
8: PID control setting
Select process PID control output as the operating frequency. Generally it is used for
closed-loop control, such as constant pressure closed-loop control, constant tension closed-
loop control and other occasions.
Select PID as the frequency source, you need to set E2 group "PID function"
parameters.
9: Remote communications setting
PI9000 supports Modbus communication.
Communication card must be installed when using the function.
The instructions for use refers to F0.03.
When the frequency source auxiliary setting is used as overlays reference (select
frequency source as master+auxiliary , master to master+auxiliary or auxiliary to
master+auxiliary ), you need to pay attention to:
1) When the frequency source auxiliary setting is set to digital reference, the preset
frequency (F0.01) does not work, user can adjust frequency by using ▲, ▼ keys (or multi-
