7. Change multiple function code parameters and status parameters of the drive, and the parameter 
values will be saved after power off.   
The command code 0x43 is used to change multiple function code parameters or control parameters of the 
drive, and store the values into the nonvolatile memory cell.   
Its command format is the same as that of 0x10. The only difference is as follows: the parameter value 
changed under the 0x10 command will not be saved upon power off, but the parameter value changed under 
the 0x43 command will be saved upon power off.   
6. Control parameters and status parameters of drive   
The control parameters of the drive can realize the start, stop, running frequency setting and other functions of 
the drive. Inquiring the status parameters of the drive can get the parameters like the running frequency, 
output current and output torque of the drive, etc.   
1. Control parameters 
The control parameters of the drive are as shown in the following table:
