Multiplex system control
System definition is configured using the function code o33 "Multi-system
control method".
0: Single-winding motor drive (Factory default)
1: Multiwinding motor control system
2: Multiplex system 1 (Direct parallel connection control system)
3: Multiplex system 2
4, 5: Reserved
Switching between multiwinding
and single-winding motor drive
Dynamic switching by digital input signal MT-CCL
Station address setting
The inverter station address is set using the function code o50 "Multi-system
station address setting".
For example, set the master to "0", slave 1 to "1", and slave 2 to "2".
Slave count setting
The number of optically linked slaves is set using the function code o34
"Multi-system slave count setting". For example, when four inverters are
linked, the number of slaves is "3".
Functional restrictions
1) The multiplex system cannot be configured with inverters of different
capacities.
2) The multiplex system cannot be configured together with older series of
inverters (VG5, VG7).
3) The multiplex system disables the following functions.
- Motor parameter tuning function (H01)*
- Auto-reset function (H04)
- Protective function for output phase loss
O0pl
(H103, tenth digit)
- Online tuning function (P32, A52, A152)
- Phase sequence configuration of main circuit output wires (H75)
The direct parallel connection control system is available. Note that the
multiplex slave units have restrictions on I/O and monitors. See Section
6.6.7.
4) In the direct parallel connection control system, the carrier frequency is
fixed at 2 kHz. Function code F26 (Motor sound, Carrier frequency)
allows the setting other than 2 kHz; however, the carrier frequency is
internally fixed at 2 kHz.
