The 3G3AX-MX2-DRT-E allows controlling, monitoring and parameterization
of an MX2-A@ Inverter via a DeviceNet network. The 3G3AX-MX2-DRT-E
serves as a gateway that passes communicated register values from the
DeviceNet network to the MX2-A@ Inverter and vice versa. The
3G3AX-MX2-DRT-E adheres to the DeviceNet / CIP AC Drive profile.
The following functions are available via DeviceNet communication by install-
ing the 3G3AX-MX2-DRT-E:
The DeviceNet Master and 3G3AX-MX2-DRT-E can exchange data via a
DeviceNet Remote I/O connection:
• Output data (from DeviceNet Master to 3G3AX-MX2-DRT-E):
E.g. Run/stop, Reference frequency and Fault reset.
• Input data (from 3G3AX-MX2-DRT-E to DeviceNet Master):
E.g. Inverter status, Output frequency and Output current, etc.
The DeviceNet Master can read and write parameter data via the
3G3AX-MX2-DRT-E using the explicit message communication.
The inverter parameters are accessible in multiple ways:
• Access based on Function code
• Access based on the Modbus register address
Several AC Drive profile attributes can also be accessed using the explicit
message mechanism.
The 3G3AX-MX2-DRT-E can be set up easily, just by wiring the Unit, setting
the DeviceNet node address (P192) and the default connection path (P046)
and restarting the unit. The Unit's configuration is read automatically when the
power is turned ON or after a reset. It is not necessary to make any settings
with a special Programming Device.
All parameters required by the 3G3AX-MX2-DRT-E are stored in the MX2-A@
Inverter. The 3G3AX-MX2-DRT-E can be replaced, requiring no re-configura-
tion.
The 3G3AX-MX2-DRT-E automatically detects the Master's communication
baud rate, and no user configuration is required.
Note If the DeviceNet Master Unit's baud rate changes, reset the Master Unit and
be sure to turn OFF and ON or reset the 3G3AX-MX2-DRT-E and other con-
nected Slave Units to detect the new baud rate.
