Using Automatic Bit Rate Detection

Note:
Available in option software version 3102 and later.
Set F6-36 = 0 [CANopen Communication Speed = Auto-detection] to enable automatic
bit rate detection and cycle the drive power supply. When set to automatic bit rate
detection, after power up the option will listen to messages on the bus and adjust its bit
rate setting automatically.
When the bit rate is found the option will enter pre-operational status and transmit a boot
up message containing the drive's node ID. The option will not send any messages until
the bit rate is detected.
As long as the automatic bit rate detection is in progress, the RUN and ERR LEDs on the
option will flicker alternately.
Note:
• There must be bus traffic that the SI-S3 can listen to in order to detect the bit rate. If there is low traffic, the bit
rate detection can take a long time.
• The bit rate detected by the SI-S3 is not automatically saved. When cycling the drive power supply, the SI-S3
will do bit rate detection again.
• In addition to the master, there must be at least one other node in the network that is set to the correct bit rate.
For example, the bit rate cannot be detected if the network consists of a master that is set up for a certain bit
rate (controller) and one or more drives with the option set to auto bit rate detection.
◆

Node ID Setup

The node ID can be set in F6-35. The value range is 1 to 126. Each node ID may only be
used once in the network.
After changing F6-35, cycle the drive power supply to enable the changes.
