Presentation
The ER23 can be connected directly to Modbus and CANopen buses by means of an RJ45 connector, which supports both protocols. The
communication function provides access to the drive’s configuration, adjustment, control and monitoring functions.
The "Communication variables" User's Manual defines the drive control processes and the drive variables which can be accessed by these
buses.
It supplements each of the following manuals:
• Modbus
• CANopen
• Profibus
• DeviceNet
These documents should be referred to for the hardware and software setup specific to each bus.
We also recommend consulting the Programming Manual for additional explanations (operation, factory settings, etc).
If the SoMove software workshop is used, consult the on-line help provided.
The communication variables are listed with:
• their address •••• in decimal format for Modbus and Profibus,
• their index and subindex address ••••/•• in hexadecimal format for CANopen.
The rule to get the DeviceNet address from the Modbus address is described in the DeviceNet manual.
They are grouped into several different tables according to the following criteria:
• IEC 61800-7 (CiA 402)
• control variables
• monitoring variables
• identification variables
• configuration and adjustment variables
Read/write
Whether the parameters have read and/or write access is indicated in the "Read/Write" column with the following codes:
• R: read only, drive stopped or running
• R/WS: read access when drive stopped or running and write access only when drive stopped
• R/W: read and write access when drive stopped or running
Authorized addresses
WARNING
LOSS OF CONTROL
Only the addresses and values defined in this document can be used. Any other address or value must be considered to be reserved
and must never be written to.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
