  SYNC loss detection (using communication cycle time. • The CANopen option module offers an SDO->parameter channel with which all of the MICROMASTER 420/430/440 parameters can be read or written into. In this case, it does not involve CANopen objects, as the numbering of the sub- indices differs with respect to CAN-open (subindex 0 does not contain the number of objects, but already the first object).

• Page 11: General Can/Canopen Definitions

  Issue 01/05 General CANopen definitions General CAN/CANopen definitions CAN (Controller-Area-Network) Apart from its use in mobile systems, the Controller-Area-Network (CAN) protocol is also deployed in other applications when allied to additional specific and standardized higher protocol and profile specifications. Alongside its use as an internal bus in mobile systems, its other main applications are in internal communication between plant and machinery.

• Page 12
  General CANopen definitions Issue 01/05 Multi-Master capability Bus access rights are not issued by a meta-level control unit (bus master) per network. Each participant can rather start to send a message with equal rights as soon as the bus has become free. If several participants access the bus at the same time, an arbitration process allocates each participant the bus access right in line with the priority of the message they want to send at that particular moment.

• Page 13: Canopen

  Issue 01/05 General CANopen definitions CANopen CANopen is a standardized application for distributed industrial automation systems based on CAN as well as the CAL communication Standards. CANopen is a CAN Standard in automation (CiA), and just shortly after it became available, enjoyed widespread use.

• Page 14: General Information

  MICROMASTER types, different CANopen modes from the DSP 402 profile (Drives and Motion Control). For MICROMASTER 420/430), only the Velocity Mode is available. The MICROMASTER 440 supports the Velocity Mode and Profile Torque Mode modes. When transferring net data via CANopen, a differentiation is made between process data (PDO) and parameter data (SDO).

• Page 15
  Issue 01/05 General CANopen definitions The COB IDs of the PDOs can be changed by changing the node address or by writing into the communication objects. If the COB ID is changed in a communications object, then this is only saved in the volatile memory. This means that if the MICROMASTER drive unit is isolated from the supply voltage, these settings are lost and, after run-up, must be re-set via the bus.

  The cause of this error is that the bus loading is too high. Reduce the rate at which messages are sent to the MICROMASTER 420/430/440. Allow at least 1ms between 2 consecutive messages to the MICROMASTER 420/430/440. Note that within the drive CANopen module PDO message data is transferred to the drive every 8 ms, so writing to the same location (i.e.

  Further Information: If object 1006H > 0, then sync checking is enabled on the MICROMASTER 420/430/440. If a sync is not received within 1.5 time the communication cycle period then this warning will occur. In response to a sync loss the user has options to ignore the error, trip the Drive, stop the drive, and/or send an emcy message.
