Application:
The online transfer of cam data to the drive controller is used if the number of cams that can be stored in the drive controller is inadequate or cam data is calculated in PLC operation. Basically any value transferred on the CAN bus is acknowledged by an ACK. If transfer does not take place properly, there will be a rejection in the form of NOK. On account of the motion profiles determined by the cams care must be taken to ensure correct transfer and in case of doubt the entire transfer must be repeated.
Description:
To facilitate diagnosis, additional error messages are generated as of software version CAM V3.2. These are assigned to the respective bus system (see also SHB TEIL E Section 8.5). The diagnostic possibilities vary enormously depending on the bus system selected. For the system bus the following messages are not defined. Here are examples of these messages for CAN module 2171/2172.
1. ILL_OPERATING_ACCESS.{10080306}: The access to cam data is locked by a password.
2. INV_LENGTH_RANGE .......{100B0306}: Data field length not allowed (depends on code and type of access)
3. INV_COLLISION_RANGE....{100C0306}: Data access not allowed (depends on code and type of access)
4. INV_VALUE_RANGE..........{100D0306}: Value of code not within permitted range
5. INV_RANGE........................{100E0306}: No consistent data can be generated
6. NOK....................................{10FF0306}: General error
7. INV_WRITE_ACCSESS.......{10090306}: Attempt to write to a read code
To avoid uncontrolled rotary motions after switching over to the reloaded cam data the data can be verified before activation.
