15 CAN Open
An alternative to the SBCCAN protocol is CANopen (to be expressly requested when placing
your order: the drive may only have one protocol at a time) with the following
implementations and functions:
The following objects are available based on CANopen’s Pre-defined Connection Set:

Drive address (Pr49), valid values 1..127.
An alarm message and two pop-up messages are available for this object, and each of these
can be enabled or disables by setting the appropriate commands.
- Alarm message
(enabled if b150.1=1)
- Target position reached
(enabled if b150.5=1)
- Value motor captured
(enabled if b150.7=1)
The alarm message, if enabled, is sent each time that the current alarm status (Pr[23])
changes, so that when a new alarm occurs (or when the alarms are reset) the value 0x01 is
sent to the field Err.Reg, and the least significant byte of the Data field will contain the drive’s
alarm code.
