External fault

Description
The "External Faults 1-6" function blocks can be used to monitor any
statuses and/or external devices, to generate fault messages and, if
necessary, to switch off the motor. To do this, the inputs (plugs) of the
"External Fault" function blocks must be connected to any sockets (e.g.
device inputs, control bits from PROFIBUS DP , etc.). External faults can also
be "marked" in SIMOCODE pro. This facilitates their allocation to the actual
malfunction. Example: Monitoring the rotational speed of the motor using
an external speed monitor.
The "External Fault" function block consists of:
• Two plugs (1 plug for setting, 1 plug for resetting)
• One "Event - External fault" socket. This is set when a signal is pending at the
input.
Overall, the following are available:
– Four "External Faults 1 to 4" function blocks for BU1
– Six "External Faults 1 to 6" function blocks for BU2.
