Input
Description
EDM feedback signal
Data type: Boolean
The input is connected to the feedback signal of the external switching
amplifier.
The general expectation is that the EDM feedback signal will assume
the inverted value of the
Control input
input within the maximum feed‐
back delay time that has been configured.
Table 86: Outputs
Output
Description
Enable
Data type: Boolean
The output controls the external switching amplifier.
•
If the
Control input
input = 0 or the
Status
output = 0, then the
Enable
output = 0.
•
If the
Control input
input = 1 and the
Status
output = 1, then the
Enable
output = 1.
Status
Data type: Boolean
The output indicates whether the
EDM feedback signal
input has switched
correctly after a change in the
Enable
output.
•
If an error occurs, then the
Status
output = 0
•
If a valid reset condition is present, then the
Status
output = 1.
Table 87: Parameter
Parameter
Description
Max. response delay
1 ms … 60 s
Maximum permitted delay until the feedback signal = 1.
Values that are not a multiple of the logic execution time are rounded
to the nearest multiple of the logic execution time.

Turn-on monitoring
If a rising edge of the
Enable
output is present, the function block
monitors whether the
EDM feedback signal
input switches to 0 within
the configured
Max. response delay
.
•
Turn-on monitoring and turn-off monitoring
In addition to Turn-on monitoring:
If a falling edge of the
Enable
output is present, the function block
monitors whether the
EDM feedback signal
input switches to 1 within
the configured
Max. response delay
.
