Note: Please set functions code related to communication consonant with the PLC/PC communication
parameters, when inverter communicates with PLC/PC.
The command from PC will be written into data memory of servodrive Immediate, it is not good to write the data
into the memory continuously.
Permission of Read&Write:
Parameter Remarks
Po505
0
Permission of Read &Write, the communication data is allowed to be written into data
register.
1
Prohibition of Read&Write, the communication commands are only executed, but they are
not allowed to be written into data register. If the servodrive is power off, data will be lost
and they need to be written again.
