C.9 MEMOBUS/Modbus Data Table

Table below lists all MEMOBUS/Modbus data. There are three types of data: command data, monitor data, and
broadcast data.
◆ Command Data
It is possible to both read and write command data.
Note: Bits that are not used should be set to 0. Refrain from writing to reserved registers.

H5-12 = 0: Forward Run Command (0 = Stop, 1 = Forward Run)
H5-12 = 1: Run Command (0 = Stop, 1 = Run)
H5-12 = 0: Reverse Run Command (0 = Stop, 1 = Reverse Run)
H5-12 = 1: Forward/Reverse (0 = Forward, 1 = Reverse)
Option Card External Fault (EF0)
Fault Reset
Multi-Function Input 1
Function is ComRef when H1-01 = 40 (Forward/Stop).
Note: When the bit at ComCtrl is turned on, commands from MEMOBUS/Modbus communications take control of the operation.
However, when a communications option card is connected, that option card is given priority.
Multi-Function Input 2
Function is ComCtrl when H1-02 = 41 (Reverse/Stop).
Multi-Function Input 3
Multi-Function Input 4
Multi-Function Input 5
Multi-Function Input 6
Multi-Function Input 7
Multi-Function Input 8
Reserved
Units are determined by parameter o1-03.
Unit: 0.1%
Range: 20 (2.0%) to 2000 (200.0%), Default when power on: 1000 (100.0%)
