CONTROL OPTIONS
o50 Multiplex System (Station address assignment)
o50 assigns the station address of an inverter unit in the multiplex system configuration (optical
communication, multiwinding control). When o59 = 0, the inverter unit is defined as a master; when o59 ≠
0, it is defined as a slave.
A setting discrepant in the system configuration, such as o50 > o32, causes an alarm
er6
.
ｏ ５ ０ Ｍ Ｗ Ｓ Ｓ Ｔ － Ｎ Ｏ
Data setting range: 0 to 5
Data setting range 0: Master station
1: Slave station 1
2: Slave station 2
3: Slave station 3
4: Slave station 4
5: Slave station 5
The selection states of master and slave units can be checked with the following.
1. Digital signal MSS status (Multiplex system master selected)
On the inverter unit that is defined as a master, the MSS signal is ON.
2. Menu #3 "OPR MNTR," page 3, (5) Drive control on the keypad
Refer to Table 3.4-8, item (5) in Chapter 3.
On page 3 in Menu #3, the selection states of master and slave units can be checked.
Configuration example
(1) 2-unit system
Set o34=1 for all systems.
(2) 4-unit system
Set o34=3 for all systems.
Note: Set the multi-system station addresses
(o50) in the order connected to the
master.
<Bad setting example>
Master (o50=0), slave 1 (o50=2
)
Slave 2 (o50=1
), slave 3 (o50=3)
* Bad setting is underlined.
Figure 6.6.9
When the o34 setting is not correct, no alarm occurs or the system may not operate. Check the setting
again.
