4.2.6 Beispiel für FU das Ein- / Ausschalten des Frequenzumrichters
In this example, a FI will be operated with a setpoint (setpoint frequency) and an actual value (actual
frequency). The "Maximum Frequency" is 50Hz.
Parameter settings:
 P105 = 500
 P543 = 1
 P546 = 1

FI is set to "Standby" status, the motor runs up its
parameterised ramp to speed 0 and is switched off.
The FI is disabled again and the motor is without current.

FI is set to "Operation enabled" status and controlled with a
25% setpoint.
The FI is enabled, the motor is supplied with current and rotates with a frequency of 12.5Hz.

4.2.7 Timeout monitoring
Data traffic on the EtherCAT side is monitored by EtherCAT watchdogs. Monitoring via the FI parameter
P513 is also possible.
P513 monitoring is triggered if the process data contact is interrupted or the process data is transferred with
an invalid control word (Bit10 in control word = 0). This function is activated when the first valid process data
telegram is received.
