Reset and Autoreset operation
If the AC drive is in Stop Mode due to a trip condition, the
AC drive 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 AC drive 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 AC drive 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 AC drive.
The examples given in this and the following paragraphs
follow the input selection shown in Fig. 72.
Fig. 72 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 AC drive stops
according to the selected Stop Mode. Fig. 73 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.
See Fig. 72. The Enable and Stop input must be active
continuously in order to accept any run-right or run-left
command. The last edge (RunR or RunL) is valid. Fig. 74
gives an example of a possible sequence.
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.
