36 Main Features
Fig. 39 Functionality of the Stop and Enable input
Reset and Autoreset operation
If the VSD is in Stop Mode due to a trip condition, the
VSD can be remotely reset by a pulse (“low” to “high”
transition) on the Reset input, default on DigIn 8.
Depending on the selected control method, a restart
takes place as follows:
Level-control
If the Run inputs remain in their position the VSD will
start immediately after the Reset command is given.
Edge-control
After the Reset command is given a new Run command
must be applied to start the VSD again.
Autoreset is enabled if the Reset input is continuously
active. The Autoreset functions are programmed in
menu Autoreset [250].
Run Inputs Level-controlled.
The inputs are set as default for level-control. This
means that an input is activated by making the input
continuously “High”. This method is commonly used if,
for example, PLCs are used to operate the VSD.
The examples given in this and the following para-
graphs follow the input selection shown in Fig. 40.
Fig. 40 Example of wiring for Run/Stop/Enable/Reset inputs
The Enable input must be continuously active in order
to accept any run-right or run-left command. If both
RunR and RunL inputs are active, then the VSD stops
according to the selected Stop Mode. Fig. 41 gives an
example of a possible sequence.

Run Inputs Edge-controlled
Menu [21A] Start signal Level/Edge must be set to
Edge to activate edge control. This means that an input
is activated by a “low” to “high” transition or vice versa.
NOTE: If the control commands are programmed for
Keyboard control or Com, Autoreset is not possible.
CAUTION: Level-controlled inputs DO NOT
comply with the Machine Directive, if the inputs
are directly used to start and stop the machine.
