Table 6.10 Modbus Communications Command Data
When H5-12 = 0, Forward run/stop
1: Forward run, 0: Stop
When H5-12 = 1, run/stop
1: Run, 0: Stop
When H5-12 = 0, Reverse run/stop
1: Reverse run, 0: Stop
When H5-12 = 1, Forward/Reverse run
1: Reverse, 0: Forward run
External Fault
1: EF0 [Option Card External Fault]
Fault Reset
1: Reset command
Multi-function input 1
When H1-01 = 1 [Forward Run], the multi-function input command is "ComRef."
Note:
When you switch the bit ON as ComRef, the frequency reference source changes to Modbus communications. When you
connect a communication option to the drive, the frequency reference source gives priority to the communications option.
Multi-function input 2
When the multi-function input command is H1-02 = 2 [Reverse Run], bit 5 is "ComCtrl."
Note:
When you switch the bit ON as ComCtrl, the Run Command source changes to Modbus communications. When you
connect a communication option to the drive, the Run Command source gives priority to the communications option.
