・Function
These parameters set up a data communications network by connecting inverters to one
another and to a host control system, and also establish a data communications link
between a computer and each inverter.
＜Computer link＞
The function is to enable data communications between a host control system (computer)
and each inverter.
① Monitoring of inverter status (output frequency, current, voltage, etc.)
② Command to each inverter (start command, stop command, etc.)
③ Load, modify, and save of inverter's parameter setting
＜Inter-drive communication＞
Designed to enables an inverter (master) to send data selected with parameters to the
other inverters (slaves) on the network. With this function, you can establish a network
to perform simplified synchronous or proportional operation (point frequency setting).
☆Timer function ....Designed to detect broken communications cables. With this function,
☆Broadcast communication ... Designed to send data to more than one inverter at a time.
☆Inter-drive communication ...The master inverter transmit the data that was chosen with
6.30.1 Common serial optional device
With RS232C unit (optional), and RS485 unit(optional), connect inverters to a higher-order
control system (host computer) to establish a data communications network between them.
Also, you can establish a data communications link between a computer and each
inverter(RS485).
☆the common serial options available:
･ RS232C communications converter units (model: RS2001Z)
Communication cable (model: CAB0011 (1 m), CAB0013 (3 m), CAB0015 (5 m))
･ RS485 communication converter unit (model: RS4001Z, RS4002Z)
Communication cable (model: CAB0011 (1 m), CAB0013 (3 m), CAB0015 (5 m))
(Note) Distance between Inverter and a common serial option should not be more than 5 m apart.
you can set the inverter in such a manner that it can trip ("" is
displayed) or an alarm goes off. ("" is displayed on the panel) if it
receives no data within the predetermined time.
the parameter to all the slave inverters on the same network.
Using this function, the network that performs synchronized
operation and proportion operation (point frequency setting) in
simple way can be constituted.
