7.2.5 Frequency Input FI
The behaviors of the analog input and frequency input are described in details in
on page
12-6. Thus, after the proper signal treatment, it is applied to the ramp input according to the selection of
the reference described in
on page
7-1.
7.2.6 "13-Bit Speed" Reference
The 13-bit Frequency Reference is a scale based on the motor rated frequency (P402) or on the motor rated
frequency (P403). In the CFW100, parameter P403 is taken as the base to determine the frequency reference.
Thus, the 13-bit frequency value has a range of 16 bits with signal, that is, -32768 to 32767; however, the rated
frequency in P403 is equivalent to the value 8192. Therefore, the maximum value in the range 32767 is equivalent
to four times P403.
The 13-bit frequency reference is used in parameters P681 and P683, which are related to the interfaces with
communication (Serial/USB) of the product.
7.3 CONTROL WORD AND INVERTER STATUS
The inverter control word is the grouping of a set of bits to determine the commands received by the inverter from
an external source. On the other hand, the status word is another set of bits that define the inverter status. This
way, the control and status words establish an interface for the exchanging of information between the inverter
and an external module, such as a communication network or a controller.
