Answer:
Example 3: Reset the parameter to the factory value , set 1 in F0-17 , and restore the parameter to the factory value
Answer:
Data frame field description :
Idles greater than 35 character transfer times
Communication address range: 1 to 247;
03: Read slave parameters; 06: Write slave parameters ;
10 : Write a group of parameters continuously
The parameter address inside the inverter , expressed in hexadecimal; it is divided into parameter
type and non-parameter type (such as running state parameters, running commands, etc.)
parameters, etc., see the address definition for details. When transmitting, the high byte comes first
and the low byte follows.
The number of parameters to be read in the frame, if it is 1, it means to read 1 parameter. When
transmitting, the high byte comes first and the low byte follows. When the command code is 0 3 , this
protocol can only rewrite one parameter at a time, and there is no such field.
The data to be answered, or the data to be written, is transmitted with the high byte in front and the
low byte in the back.
Detection value: CRC16 check value. When transmitting, the low byte comes first and the high byte
follows.
For the calculation method, please refer to the description of CRC check in this section.
5.Parameter parameter address marking rules
The rule is represented by the parameter group number and label as the parameter address:
High byte: 00~0F (group F), 70 ( group d )
Low byte: 00~FF
For example: to access parameter F3-12, the access address of the parameter is represented as 0x030C;
Note: FP group: parameters can neither be read nor changed;
Group d : can only be read, parameters cannot be changed.
Some parameters cannot be changed when the inverter is in the running state; some parameters cannot be changed
regardless of the state of the inverter; when changing the parameters, pay attention to the range, unit and related
