CAN identifier for PZD-receive broadcast
With this parameter, the CAN identifier for PZD-receive broadcast (receiving
process data = setpoints / control words) can be set. A broadcast telegram is
to be received by all slaves on the bus. This parameter must be set the same
for all slaves.
Because only four setpoints (= 8 bytes) can be sent with a CAN data telegram
but 16 setpoints are supported by MASTERDRIVES units, a total of four CAN
data telegrams with four CAN identifiers are needed for transferring the
setpoints. The following three CAN identifiers are therefore also provided for
PZD-receive broadcast. The following table applies:
Contents CAN identifier
Control word 1 / Setpoint 2 / Setpoint 3 / Setpoint 4 or
Control word 2
P716/P701
Setpoint 5 to Setpoint 8
P716/P701 + 1
Setpoint 9 to Setpoint 12
P716/P701 + 2
Setpoint 13 to Setpoint 16
P716/P701 + 3
With the value 0 (pre-assigned) in this parameter, PZD-receive broadcast is
deactivated.
If the calculated CAN identifier for PZD-receive broadcast is outside the valid
range (1 to 2000) or if it overlaps another CAN identifier, error F080 appears
when status 4 "hardware configuration" is left. After acknowledgement of the
error, you are in the "hardware configuration" status again and can correct the
incorrect parameterization.
Example:
The CAN identifier for PZD-receive broadcast in P716 / P701 is set to 100.
This results in a CAN identifier of 100 for the first CAN data telegram of PZD-
receive broadcast. The further CAN data telegrams for PZD-receive
broadcast have CAN identifiers 101 to 103.
