5-42 Off Delay, Relay
Array [9] (Relay 1 [0], Relay 2 [1], Relay 3 [2], Relay 4 [3], Relay 5 [4],
Relay 6 [5], Relay 7 [6], Relay 8 [7], Relay 9 [8])
Range: Function:
0.01 s [0.01 - 600.00 s] Enter the delay of the relay cut-out
*
time. Select one of available mechanical
relays and MCB 105 in an array
function. See 5-40 Function Relay.

If the selected Event condition changes before the on- or off
delay timer expires, the relay output is unaffected.
3.7.5 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 (5-13 Terminal 29 Digital Input) or
terminal 33 (5-15 Terminal 33 Digital Input) to Pulse input [32].
If terminal 29 is used as an input, then set 5-01 Terminal 27
Mode to Input [0].

5-54 Pulse Filter Time Constant #29
Range: Function:
100 [1 - 1000 Enter the pulse filter time constant. The pulse
ms ms] filter dampens oscillations of the feedback
*
signal, which is an advantage if there is a lot
of noise in the system. A high time constant
value results in better dampening but also
increases the time delay through the filter.
This parameter is available for FC 302 only.
This parameter cannot be adjusted while the
motor is running.
Function:
Enter the low reference
value limit for the motor
shaft speed [RPM]. This is
also the lowest feedback
value, see also 5-57 Term.
33 Low Ref./Feedb. Value.
Set terminal 29 to digital
input (5-02 Terminal 29

value).
This parameter is
available for FC 302 only.
Function:
Enter the high reference

shaft speed and the high
feedback value, see also
