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.
Note:
When the node is set to 0, the ERR light will flash and "AEr" will appear on the drive keypad to indicate that an address setting error has
occurred.
