301 DIN3 function
(2.2.2)
0 Not used
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 = Motor start disabled and the motor is stopped
contact closed = Motor start enabled
4 Acc./Dec contact open = Acceleration/deceleration time 1 selected
time select. contact closed = Acceleration/deceleration time 2 selected
5 Closing contact: Force control place to I/O terminal
6 Closing contact: Force control place to keypad
7 Closing contact: Force control place to fieldbus
When the control place is forced to change the values of Start/Stop, Direction and
Reference valid in the respective control place are used (reference according to
parameters
ID117 , ID121 and ID122 ).
Note: The value of parameter ID125 Keypad Control Place does not change.
When DIN3 opens the control place is selected according to parameter 3.1.
8 Reverse contact open = Forward
contact closed = Reverse
302 Reference offset for current input
(2.2.3)
0 No offset: 0—20mA
1 Offset 4 mA (“living zero”), provides supervision of zero level signal. In Standard
Application, the response to 4 mA reference fault can be programmed with
parameter
ID700 .
303 Reference scaling, minimum value
(2.2.4)
304 Reference scaling, maximum value
(2.2.5)
Setting value limits: 0
≤
P ID303
≤
P ID304
≤
P ID102 . If parameter ID303 = 0 scaling is
set off. The minimum and maximum frequencies are used for scaling.
Figure 5-6. Left: Reference scaling; Right: No scaling used (P ID303 = 0).
Can be used for reversing if
parameter
ID300 has value 3.
