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

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
