Description
0000 Reserved
0001
Run command, multi-function input command
bit 0
When H5-12 = 0, Forward run/stop
1: Forward run, 0: Stop
When H5-12 = 1, run/stop
1: Run, 0: Stop
bit 1
When H5-12 = 0, Reverse run/stop
1: Reverse run, 0: Stop
When H5-12 = 1, Forward/Reverse run
1: Reverse, 0: Forward run
bit 2
External fault
1: EF0 [Option Card External Fault]
bit 3
Fault Reset
1: Reset command
bit 4
Multi-function input 1
When H1-01 = 40 [Forward Run Command (2-Wire Seq)], the multi-function input command is “ComRef.”
Note:
When you switch the bit ON as ComRef, the frequency reference source changes to MEMOBUS/Modbus
communications. When you connect a communication option to the drive, the frequency reference source gives priority to
the communications option.
bit 5
Multi-function input 2
When the multi-function input command is H1-02 = 41 [Reverse Run Command (2-Wire Seq)], bit 5 is “ComCtrl.”
Note:
When you switch the bit ON as ComCtrl, the Run Command source changes to MEMOBUS/Modbus communications.
When you connect a communication option to the drive, the Run Command source gives priority to the communications
option.
