6.3 Basic functions of the SED2

6.3.1 Digital inputs
External switch-on and switch-off arrangements are required for stand-alone operation
of variable speed drives. The digital input port provides six channels, which can be
extended to eight by use of the two analog inputs.
You can program the function of the digital inputs as required.

P0701 to P0706
Digital inputs 1 to 6
The available settings for each of the input channels are listed below:
0 Digital input disabled.
1 ON / OFF1 – OFF as per the ramp-down time defined in P1121.
2 ON + change direction of rotation / OFF1.
3 OFF2 – coast to standstill.
4 OFF3 – faster ramp-down (quick stop = ramp-down at power limit).
9 Error acknowledgement.
10 JOG right.
11 JOG left.
12 Reverse direction of rotation.
13 Motor potentiometer (MOP) higher (increased frequency).
14 Motor potentiometer (MOP) lower (reduced frequency).
15 Fixed setpoint (binary coded).
16 Fixed setpoint (binary coded + ON).
17 Fixed setpoint (binary-coded decimal + ON).
25 Enable DC braking.
26 Enable Essential Service.
