*) not effective when using 8200 vector or 93XXcontrollers
This code contains a selection which indicates at which event the TPDOs CAN−OUT1 ... 3 are
to be sent. It is possible to make an individual selection for each TPDO by dividing the code
in subcodes.
ƒ Value = 0:
– The TPDOs are sent when a sync telegram has been received.
– Under code C1874/C2374 you can set that the TPDOs are only to be sent after the
n−th sync telegram (n = 1 ... 240).
ƒ Value = 1:
– TPDOs are not sent.
– With this selection the transmission of TPDOs is deactivated.
This is useful for 8200 vector and 9300 drives which are only able to exchange four
words as a maximum of control and status information via the AIF. For this
purpose, the use of one TPDO is sufficient, TPDOs 2 and 3 are deactivated (Lenze
setting). This avoids an unnecessary load of the CAN bus.
ƒ Value = 2:
– The corresponding TPDO is either transmitted event−controlled or cyclically.
– The TPDO is transmitted cyclically if a cycle time is defined for the TPDO under
code C1856/C2356. If the cycle time is zero, the TPDO is sent in case of an event,
i.e. bit change within the TPDO.
ƒ Value = 3:
– The TPDO is event−controlled and cyclically transmitted. This means that the
object is transmitted with the cycle time defined under code C1856/C2356.
– In addition, the object will be transmitted if one or several bits are changed within
the TPDO.
)
Note!
If the transmission is event−controlled (also with cyclic superimpositions) some
bits can be hidden by masking the object using codes C1876 ... C1878 or with
the 9300 Servo PLC, Drive PLC and ECS C2376 ... C2378. This means that the
TPDO will not be sent when a bit is being changed.
