Adjust and Function Specification
§ Cd77 KW-Hour and MW-Hour reset memory (setting range 0~1)
When set Cd79=1, KW-Hour and MW-Hour will be recorded automatically when the
power off. When set up successfully, “CLr” will showed, and the record will be cleared
to zero.
§ Cd79 auto saving function setting (setting range 0~1)
This function can’t be modified during revolution.
Cd79=0 Disable auto saving
Cd79=1 Enable auto saving. When power off KW-Hour, MW-Hour, Hanks counter,
Current time of PLC and current step PLC will be recorded automatically.
§ Cd80 Modbus Protocol and communication mode setting (settable range 0-6)
This function can’t be modified during revolution.
Selection of operation method on RS485 communication port. Supporting Modbus
Protocol.
Cd80=0 RS485 shut down communication interface.
Cd80=1 Active RTU Mode. Parameter change is not allowed.
Cd80=2 Active RTU Mode. Allow changes on general parameter.
Cd80=3 Active RTU Mode. Allow changes on operation instruction and general
parameter.

Setting of Baud rate during communication
Cd82=0 2400 bps
Cd82=1 4800 bps
Cd82=2 9600 bps
Cd82=3 19200 bps
Note: Re-start inverter after setting Baud rate.
§ Cd83 Series communication response time setting（settable range 0-15）
This function can’t be modified during revolution.
Setting waiting time for response when inverter receive correction data.
MODBUS RESPONE TIME=(0 ~ 8ms) + (8ms * CD83)
