Remote control functions
Operation of the Run/Stop/Enable/Reset functions
As default, all the run/stop/reset related commands are programmed for
remote operation via the inputs on the terminal strip (terminals 1-22) on the
control board. With the function Run/Stp Ctrl [215] and Reset Control [216],
this can be selected for keyboard or serial communication control.
Note
The examples in this paragraph do not cover all possibilities. Only the most
relevant combinations are given. The starting point is always the default
setting (factory) of the VSD.
Default settings of the Run/Stop/Enable/Reset
functions
The default settings are shown in Fig. 43. In this example the VSD is started
and stopped with DigIn 2 and a reset after trip can be given with DigIn 8.
Fig. 43 Default setting Run/Reset commands
The inputs are default set for level-control. The rotation is determined by the
setting of the digital inputs.
Enable and Stop functions
Both functions can be used separately or simultaneously. The choice of which
function is to be used depends on the application and the control mode of the
inputs (Level/Edge [21A]).
Note
In Edge mode, at least one digital input must be programmed to “stop”,
because the Run commands are only able to start the VSD.
Enable
Input must be active (HI) to allow any Run signal. If the input is made LOW,
the output of the VSD is immediately disabled and the motor will coast.
!Caution
If the Enable function is not programmed to a digital input, it is considered to
be active internally.
Stop
If the input is low then the VSD will stop according to the selected stop mode
set in menu [33B] Stop Mode. Fig. 44 shows the function of the Enable and
the Stop input and the Stop Mode=Decel [33B].
To run the input must be high.
