Table 6.15 MEMOBUS/Modbus Communications Command Data
Register No.
(Hex.)
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.
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 - F Reserved
0002 Frequency Reference o1-03 [Frequency Display Unit Selection] (unsigned) sets the units.
0003 Output voltage gain
Units: 0.1%
Setting range: 20 (2.0%) to 2000 (200.0%), the default value at energize: 1000 (100.0%)
0004 Torque reference/torque limit (0.1% signed)
0005 Torque compensation (0.1% signed)
0006 PID setpoint (0.01% signed)
0007 Setting for the multi-function analog monitor output terminal 1 (10 V/4000 H)
0008 Setting for the multi-function analog monitor output terminal 2 (10 V/4000 H)
