Once configured, the
producer. In case that an error is detected because the consumer stopped receiving messages from the
producer, the inverter will turn automatically to the preoperational state and indicate alarm A135 on its HMI. The
occurrence of this error can also be observed through the parameter P0721.
As a producer, the CFW-11 has an object for the configuration of that service:
The 1017h object allows programming the time in milliseconds during which the producer has to send a
telegram to the network. Once programmed, the inverter initiates the transmission of messages with the following
format:
NOTE!
This object is active even in the stopped state (see Table 5.8).
The value 0 (zero) in the object will disable this function.
If after the error detection the service is enabled again, then the error indication will be removed
from the HMI.
The time value programmed for the consumer must be higher than the programmed for the
respective producer. Actually, it is recommended to program the consumer with a multiple of the
value used for the producer.
For any every slave only one of the two services -

5.7 Initialization Procedure

Once the operation of the objects available for the frequency inverter CFW-11 is known, then it becomes necessary
to program the different objects to operate combined in the network. In a general manner, the procedure for the
initialization of the objects in a CANopen network follows the description of the next flowchart:
