UMI-B1 UL Series Inverter
Function
code
P10.00
P10.01
Note: P29 group is the factory parameter which cannot be read or changed. Some
parameters cannot be changed when the inverter is in the running state and some
parameters cannot be changed in any state. The setting range, unit and relative
instructions should be paid attention to when modifying the function code parameters.
Besides, EEPROM is stocked frequently, which may shorten the usage time of
EEPROM. For users, some functions are not necessary to be stocked on the
communication mode. The needs can be met on by changing the value in RAM.
Changing the high bit of the function code from 0 to 1 can also realize the function. For
example, the function code P00.07 is not stocked into EEPROM. Only by changing the
value in RAM can set the address to 8007H. This address can only be used in writing
RAM other than reading. If it is used to read, it is an invalid address.
7.3.5.2 The address instruction of other function in Modbus
The master can operate on the parameters of the inverter as well as control the inverter,
such as running or stopping and monitoring the working state of the inverter.
