2.2.1 Assigning the system bus node addresses to the frequency inverters
If the node addresses are assigned in continuous, ascending order to the Lenze controllers, the
default setting of the event−controlled data object identifiers (CAN2_IO/CAN3_IO) allows
communication between the controllers:
L
Node-ID 1
CAN2_OUT CAN2_IN
CAN3_OUT CAN3_IN
L
Node-ID 2
CAN2_OUT CAN2_IN
CAN3_OUT CAN3_IN
L
Node-ID 3
If you want to parameterise a group of frequency inverters with different values you have to skip at
least one node address between the inverters to interrupt the automatic data transfer:
L
Node-ID 1
CAN2_OUT CAN2_IN
CAN3_OUT CAN3_IN
L
Node-ID 3
CAN2_OUT CAN2_IN
CAN3_OUT CAN3_IN
L
Node-ID 5
·
In this way, you can parameterise a maximum of 32 frequency inverters
(with node address 1 − 3 − 5 − 7 − ... − 63).
Note!
New node addresses will only become effective after a Reset−node. (For the 8200vector frequency
inverter, e. g. under code C0358)
2.2.2 Function block activation
The FB L_8200Initialization must be called cyclically because the data are internally transmitted to
the frequency inverter via the FB L_ParWrite.
·
Depending on the amount of data to be transmitted, the data transfer may take several cycles.
·
If the data transfer has been successful, the message output bParDone will be set to TRUE.
·
When the data transfer has been completed ( bParDone = TRUE), the parameterisation is
complete and the FBs L_8200Parameter and L_8200Initialization need not be called again.
