Brief Introduction
DRn 5020 frequency converter provides standard communication interface to
realize the communication between the master and slave via Modbus,
Profibus, Profinet, CANopen, Ethernet and other protocols. With the help of a
PC, a PLC or an external computer a ''single master / multiple slaves'' net‐
work control can be realized (setting of pressure command, swivel angle
command, modification of parameters, monitoring of frequency converter run‐
ning status and error messages) to address the specific requirements of ap‐
plications.
●
Cycle time for command and status value exchanging is
2ms.
●
Bus communication and internal ASF data communication
are not synchronized.
