ACT Systembus
The ACT frequency inverter systembus is an
economical and powerful communication system
allowing the connection of up to 64 ACT inverters.
Taking account of its characteristics, the systembus
is based on CAN and is implemented along the
lines of CANopen methods. The systembus has two
SDO channels and three PDO channels.
Channel SDO1 allows access to the real parameters
and values of all the inverters in the systembus
from an external control system (e.g. PLC, NC,
etc. ). For this reason the master inverter must be
interfaced with the field bus. Channel SDO2 is used
for connection of a PC display tool for Windows.
This display tool allows parameterisation and
monitoring of the process on-line.
Data can be exchanged between inverters with
very high speed and precision by means of the PDO
channels. Data exchange can take place between
any of the inverters in the systembus.
In the case of a master/slave control, nominal
speed is transmitted from the master inverter to
the slaves. This strategy makes it possible to obtain
anadjustablespeedratiobetweenthemaster
and one or more slaves. In the case that speed
sensors are used on the master and on the slaves,
it is possible to implement a synchronous tie with
angular ratios that can be modified on-line.
