Range:
0.01 s* [0.01 - 600.00 s]
If the selected Event condition changes before the on- or off delay timer expires, the relay output is unaffected.
3.7.6 5-5* Pulse Input
The pulse input parameters are used to define an appropriate window for the impulse reference area by configuring the scaling and filter settings for the
pulse inputs. Input terminals 29 or 33 act as frequency reference inputs. Set terminal 29 (par. 5-13

This parameter is available for FC 302 only.
Function:
Enter the low reference value limit for the motor shaft speed [RPM]. This is also the lowest feedback
value, see also par. 5-57
