Illustration 7.10 Example of Setting the Update Time and Number of Accepted Lost I/O Cycles
The PROFINET interface issues warning 34, 384
milliseconds after the communication is lost. The frequency
converter issues the alarm 17, if the communication is still
missing after 3.0 s. At this time the relay 1 set to off
(
parameter 5-40 Function Relay
) and command the motor to
stop (
parameter 8-04 Control Timeout Function
), this will
then cause the motor to ramp down to stop. When the
motor is stopped the frequency converter goes into “TRIP”
state. “TRIP" state needs a reset via control word, LCP or
other sources, before the pump can be activated again.
