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.

Register No. Contents
0000H Reserved
0001H
Operation Commands and Multi-function Inputs
bit 0
H5-12 = 0: Forward Run Command (0 = Stop, 1 = Forward Run)
H5-12 = 1: Run Command (0 = Stop, 1 = Run)
bit 1
H5-12 = 0: Reverse Run Command (0 = Stop, 1 = Reverse Run)
H5-12 = 1: Forward/Reverse (0 = Forward, 1 = Reverse)
bit 2 External Fault (EF0)
bit 3 Fault Reset
bit 4
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.
bit 5
Multi-Function Input 2
Function is ComCtrl when H1-02 = 41 (Reverse/Stop).
bit 6 Multi-Function Input 3
bit 7 Multi-Function Input 4
bit 8 Multi-Function Input 5
bit 9 Multi-Function Input 6
bit A Multi-Function Input 7
bit B Multi-Function Input 8
bit C to F Reserved
0002H Frequency Reference Units are determined by parameter o1-03.
