Chapter 5 Parameter Introductions
not overlap with the address numbers of other slaves in the network. To make many
inverters and control PLC operate in the network, every inverter has its own address
number. At most 31 inverters whose address numbers are from 1 to 31can tie to control
PLC at the same time. 0 is broadcast address. The slave does not receive
communication command when Pb.01 is set to 0.
Pb.02 MODBUS parity selection
Range: 0~2【0】
0: Even parity 1: Odd parity
2: No parity
Pb.03 MODBUS time over detection
Range: 0~100.0s 【0.0s】
Note:
◆If Pb.03 is set to zero, this function is disabled.
◆If Pb.03 is not set to zero, overtime detection is enabled. And the detecting time is the
setting value of Pb.03. If in detecting time, abnormal data is be sent or received, the
inverter will stop immediately and display EF0. It need to manual reset.
Tips:
If in detect time the slave just receive abnormal data, it will stop and display EF0.
Range: 0~500ms【5ms】
Pb.04 Response delay time
Note:
◆It refers to the time from inverter receiving the host PC command to returning
response frame to it.
Pb.05 MODBUS frequency reference unit
Range: 0,1【0】
0:0.01Hz 1:0.1Hz
Note:
◆Used to select the frequency unit of communication command.
◆The output frequency resolution of this series inverter is 0.01Hz. If the frequency
reference unit is set to 0.01Hz in parameter Pb.05 (Pb.05=0), the unit of the received
frequency reference will be treated as 0.01Hz. If Pb.05 is set to 1 (0.1Hz), the unit of
the received frequency reference will be treated as 0.1Hz and the value will be
automatic transferred to 0.01Hz internally. For example, if the frequency command is
01F4H (the hexadecimal value of 500), it will be treated as 5.00Hz when Pb.05 is set
to 0. Or it will be automatic transferred to 50.0(0) Hz and treated as 50.00 Hz when
Pb.05 is set to 1.
Pb.06 Selection of MODBUS data storage
Range:0,1【0】
0:Not save to EEPROM 1:Directly save to EEPROM
Note:
This function code is used to select whether to save the MODBUS data to EEPROM or
not. If pb.06 is set as 1, parameters that modified by MODBUS communication will be
