2. 12 Analogue input I
in
filter time
Filters out disturbances from the
incoming analogue I
in
signal.
Long filtering time makes
regulation response slower.

2. 13 DIA5 function
1: External fault, closing contact = Fault is shown and motor is stopped when
the input is active
2: External fault, opening contact = Fault is shown and motor is stopped when
the input is not active
3: Run enable contact open = Start of the motor disabled
contact closed = Start of the motor enabled
4: Acc. / Dec contact open = Acceleration/Deceleration time 1 selected
time select. contact closed = Acceleration/Deceleration time 2 selected
5: Reverse contact open = Forward
If two or more inputs are
contact closed = Reverse programmed to reverse then
if one of them is active the
direction is reverse
6: Jogging freq. contact closed = Jogging frequency selected for freq. refer.
7: Fault reset contact closed = Resets all faults
8: Acc./Dec. contact closed = Stops acceleration and deceleration until
operation the contact is opened
prohibited
9: DC-braking contact closed = In the stop mode, the DC-braking operates
command until the contact is opened, see figure 6-1.
DC-brake current is set with parameter 4. 8.
10: PI-contr. ref. contact closed = reference 2 (selected with par. 2.29) is
selection active
11: Interlock inp. contact closed = Interlock of autochange drive 3 is active
autochange 3
2. 14 Motor potentiometer ramp time
Defines how fast the electronic motor potentiometer value changes.
