Description
Some VERSUS control panels for AC motors allow detecting motor internal limit
switches and motor blocking status.
The motor blocking status detection is used as a safety function in order to avoid the
motor activation due to a motor malfunction.
Motor internal limit switches detection function allows using the internal limit switches as
an opened/closed position references. The use of these position references ensures a
better door position control.
Configuration
To enable AC motor internal limit switches and blocking detection it is necessary to set
to ON the associated
P1E
parameter by means of a VERSUS-PROG programming tool.
There is also possible to enable/disable this function by means of assigning this function
to a one of the selector switches (
P54
to
P5C
parameters).
There are also 4 status parameters (read-only parameters) that give information about
this function. The
P1F
and the
P20
parameters are set to ON if during the programming
sequence AC motor internal switches are detected (
P1F
for the opening limit switch and
P20
for the closing limit switch).
P51
and
P52
parameters inform about the electronic
integrator circuit measured thresholds. These thresholds are measured during the
programming sequence and they take a numeric value. They can be used to check an
installation by an advanced installer or for customer service purposes.
Finally, there is another numeric configuration parameter that is used if AC motor internal
limit switches detection is enabled. This is the
P3E
parameter and it configures the extra
time/pulses that are added to search the programmed position references
