Modbus Communications
The drive’s serial communication protocol is Modbus RTU slave with a 32 bit data extension. The Modbus protocol
is available on most operator interface panels and PLC’s.
Ethernet Port
The Ethernet port at J11 has only functional isolation from other low voltage circuits and PE at the drive. In order to
classify any low voltage circuits in the drive as PELV, the ethernet circuit must be installed as a PELV circuit. Refer
to installation instructions with the hub, switch or other devices connected for details.
The system meets EMC emissions and immunity requirements using unshielded ethernet cables when a clamp on
ferrite is attached to the ethernet cable as it leaves the enclosure.
DeviceNet Port
The DeviceNet port at J9 has only functional isolation from other low voltage circuits and PE at the drive.
In order to classify any low voltage circuits in the drive as PELV, the DeviceNet circuit must also be installed as a
PELV circuit.
