Remote control functions
Section 7-2
Note
Stop Mode=Coast [33B] will give the same behaviour as the Enable input.
Fig. 44 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].
Note
If the control commands are programmed for Keyboard control or Com,
Autoreset is not possible.
Run Inputs Level-controlled.
The inputs are set as default for level-control. This means that an input is acti-
vated by making the input continuously “High”. This method is commonly used
if, for example, PLCs are used to operate the VSD.
!Caution
Level-controlled inputs DO NOT comply with the Machine Directive, if the
inputs are directly used to start and stop the machine.
The examples given in this and the following paragraphs follow the input
selection shown in Fig. 45.
