No. Name Description
o33
Multiplex system (Control
mode)
Select the control mode of the multiplex system.
o34
Multiplex system (No. of slave
stations)
Specify the number of slave stations.
o50
Multiplex system (Station
address assignment)

link terminal block (OPC-VG1-TBSI).
E01 to
E13
X Terminal Function 57: Cancel multiplex system MT-CCL
E15 to
E27
Y Terminal Function
51: Multiplex system communications link being established MTS
52: Answerback to cancellation of multiplex system MEC-AB
53: Multiplex system master selected MSS
54: Multiplex system local station failure AL-SF
o33 Multiplex System (Control mode)
o33 selects whether or not to use a high-speed serial communications terminal block OPC-VG1-TBS1 as a
component of the multiwinding system or multiplex system
Refer to MT-CCL (Cancel multiplex system) in the description of E01 to E13 (Terminal X Function).
ｏ ３ ３ Ｍ Ｗ Ｓ Ａ Ｃ Ｔ Ｉ Ｖ Ｅ
Data setting range 0: Single-winding motor drive
1: Multiwinding motor control system
2: Direct parallel connection control system
3 to 5: Reserved
o34 Multiplex System (No. of slave stations)
o34 specifies the number of slave inverter units connected via the optical fiber cable. Note that this is not
the number of all inverters including the master.
ｏ ３ ４ Ｍ Ｗ Ｓ Ｓ Ｌ Ａ Ｖ Ｅ Ｓ
Data setting range: 1 to 5
Data setting range 1: 1 master + 1 slave = System with total of 2 units
2: 1 master + 2 slaves = System with total of 3 units
3: 1 master + 3 slaves = System with total of 4 units
4: 1 master + 4 slaves = System with total of 5 units
5: 1 master + 5 slaves = System with total of 6 units
