n152
: Modbus Frequency Resolution
Factory setting: 0
Range: 0 to 3
The frequency resolution from the PLC and in the frequency reference and output
frequency monitor (by communication) are selected with this parameter. The output
frequency resolution of the GPD Drive is 0.1 Hz. Even if the Modbus resolution is
changed to 0.01 Hz in n152 , the value in the hundredths digit of 0.01 Hz of the
received frequency reference is rounded off internally. When 30,000/100% in units
of 0.1% is selected, the value is also rounded off.
n153
: Modbus Slave Address
Factory setting: 0
Range: 0 to 31
Each slave GPD Drive on the same transmission line must be given a unique address.
n154
: Modbus Baud Rate
Factory setting: 2
Range: 0 to 3
Selects the baud rate, as indicated by the following table:
Setting
Baud Rate (BPS)
0
2400
1
4800
2
9600
3
19,200
n155
: Modbus Parity Selection
Factory setting: 1
Range: 0 to 2
Selects the parity, as indicated by the following table:
