IPE300 series engineering VFD Communication protocol
-283-
0: Stop after running once
1: Keep running with the final value after running
once
2: Cyclic running
Simple PLC
memory selection
0: No memory after power off
1: With memory after power off
Note:
The parameters in the P99 group are set by the manufacturer and cannot be read or modified.
Some parameters cannot be modified when the VFD is running; some cannot be modified
regardless of the VFD status. Pay attention to the setting range, unit, and description of a
parameter when modifying it.
The service life of the Electrically Erasable Programmable Read-Only Memory (EEPROM) may
be reduced if it is frequently used for storage. Some function codes do not need to be stored
during communication. The application requirements can be met by modifying the value of the
on-chip RAM, that is, modifying the MSB of the corresponding function code address from 0 to 1.
For example, if P00.07 is not to be stored in the EEPROM, you need only to modify the value of
the RAM, that is, set the address to 8007H. The address can be used only for writing data to the
on-chip RAM, and it is invalid when used for reading data.
9.4.5.2 Address description of other function codes
In addition to modifying the parameters of the VFD, the master can also control the VFD, such as
starting and stopping the VFD, and monitoring the running status of the VFD. The following table lists
other function parameters.
Communication-based
control command
Communication-based
setting address
Communication-based frequency setting (0–Fmax;
unit: 0.01 Hz)
PID reference (0–1000, in which 1000 corresponds
to 100.0%)
PID feedback (0–1000, in which 1000 corresponds
to 100.0%)
