Page 5: Warning Against Unintended Start
Modbus TCP 1.1.4 Warning against Unintended Start The motor can be brought to a stop by means of bus commands while the variable speed drive is connected to mains. If personal safety considerations make it necessary to ensure that no unintended start occurs, these stop functions are not sufficient. While parameters are being changed, the motor may start.

Page 6: Introduction
2.1.2 Assumptions These operating instructions are under the conditions that the GE Modbus TCP option is used in conjunction with a GE AF-650 GP or AF-600 FP frequency converter, inclusive that the installed controller supports the interfaces described in this document and that all the requirements stipulated in the controller, as well as the frequency converter, are strictly observed along with all limitations herein.

Page 11: Topology
Modbus TCP 3.1.4 Topology The OPCMBTCP features a build-in Ethernet-switch, thus having two Ethernet RJ-45 connectors. This enables the possibility for connecting several Modbus TCP options in a line topology as an alternative to the typical star-topology. The two ports are equal, in the sense that they are transparent for the option. If only one connector is used, either port can be used. Illustration 3.2: Star topology Illustration 3.3: Line topology For line topology please refer to section: “Recommended design rules”...
-
Page 12: Network
Modbus TCP Please observe that mounting drives of different power-sizes in a line topology may result in unwanted power-off behaviour. Smaller drives discharge faster than bigger drives. This can result in loss of link in the line topology, which may lead to control word timeout. To avoid this, mount the drives with the longest discharge time first in the line topology.
-
Page 13: Recommended Design Rules
Modbus TCP 3.1.6 Recommended Design Rules While designing Ethernet networks special attention and caution must be taken regarding active network components. While designing a network for line topology it is important to notice that a small delay is added with each every switch in the line. It is not recommended to connect more than 32 drives in a line at any API.

Page 14: Emc Precautions
The following EMC precautions are recommended in order to achieve interference-free operation of the Ethernet network. Additional EMC information is available in the AF-650 GP/AF-600 FP series Design Guide. Relevant national and local regulations, for example regarding protective earth connection, must be observed.

Page 18: Configuring The Scanner
4.1.3 Configuring the Scanner For configuring the scanner to communicate to the drive, no system (e.g. EDS, GSD file) file is needed. The AF-600 FP/AF-650 GP is handled as a generic device an as such, it has to be configured directly in the scanner. The following example setup the scanner to IP addresses 192.168.1.20 and the AF-650 GP to address 192.168.1.20.

(blocked) state. If one network segment in the Spanning-Tree Protocol becomes unreachable, or if Spanning-Tree Protocol costs change, the spanning-tree algorithm reconfigures the spanning-tree topology and re-establishes the link by activating the standby path. Spanning-Tree Protocol operation is necessary if the AF-650 GP or AF-600 FP’s are running in a ring/redundant line topology.
