Parameter description
This parameter is valid only when the frequency source is digital setting.
When keyboard is used to determine the ▲, ▼ buttons or terminal UP / DOWN action, adopt any
manner in which the frequency correction is set, That target frequency increases or decreases based on the
operating frequency or based on the set frequency.
Difference between the two settings performs significantly when the inverter is in the process of
acceleration and deceleration. That is, if the operating frequency and the set frequency of the inverter are
not the same, the difference between different parameter selection will be large.
Frequency source and
command source in bundle
P0-27
Setting
range
It defines the bundle of three run command channel and nine given frequencies between channels, and it
is easy for the realization of synchronous switch.
The above frequencies given channel meaning is same with main frequency source X selection P0-03.
See the description of function code P0-03. Different modes can be bundled with the same frequency given
channel. When the command frequency source has bundled source, in the effective period of the command
source, P0-03 ~ P0-07 set frequency source no longer works.
Communication expansion card type
P0-28
Setting
range
VFD provides two kinds of communication. This communication requires an optional
communication card before use, and two kinds of communication can not be used at same time.
This parameter is used to set the type of the optional communication card. When the user to replace
the communications card, you must set the parameters correctly.
