6: Process closed loop PID
The frequency setting is determined by the calculation result of the process closed loop PID.
7: Multi-speed running
In this mode, when the drive is powered on, it will use the value of the function code P02.05 as the current
set frequency directly. The running frequency is determined by the terminal function, the multi-speed is
the value of P02.05 as default. Select the multi-speed running function according to the terminal function
and run with corresponding speed when the terminal input is enabled. Please refer to the explanation to
the function code for details.
8: Field bus reference
Set the reference via the field bus.
Note
The frequency calculation relationship curves for the frequency main reference modes 3 and 4 are determined
by the function code of Group P10. When the main frequency reference adopts the analog or pulse reference,
the positive and negative polarity of the output main set frequency is determined by the selection of the
function code of Group P10, which determine whether the reference adopts the analog or pulse value, or let it
determined by the function code of Group P02.03. In the contrast, when the frequency reference is provided
under other modes, the positive and negative polarity of the main set frequency is determined by P02.03
completely. The auxiliary frequency superimposition is not applicable to the output frequency for the main
frequency reference modes 5, 6 and 7. The calculation of the output frequency for these three modes are
independent.
When the main set frequency channel is defined as the digital reference (P02.04=0, 1, 2, 7), this function
parameter represents the initial set frequency of the main set frequency of the drive.
For the main reference & auxiliary reference digital frequency control, the main reference frequency
control is only enabled for P02.04=0, 1, 2, and the auxiliary reference frequency control is only enabled
for P02.07=1~3.
