BINARY PARAMETERS
Binary parameter Pb40 can be read, written and saved. Binary parameter Pb41 provides
information regarding system status. Parameters Pb42 and Pb99 are read/write parameters with save
facility.
b40.0
Selecting the first or second speed reference full scale value
.
Default=0. If set to 0
Pr2 is used to standardise the analogue reference. If set to 1 parameter Pr3 is used.
b40.1
Activation of algorithm for the suppression of vibration at 0 rpm
.
Default=0. Set to 1
to activate the algorithm.
b40.2
Selecting user/reserved reference
.
If set to 1 the reserved reference is used in
accordance with the currently active operating mode. If set to zero the reference selected by
b40.0, b40.12 and b40.13. is employed. Default is 0.
b40.3
Reference freeze
.
Default=0. If set to 1 the reference will not be updated so that motor
will not follow input reference modifications. If set to zero the reference will follow variation
in the input reference.
b40.4
Left limit-switch
.
Default=0. If set to 1 and the selected reference requires negative speed,
the reference will be forced to zero in accordance with the ramp in Pr12. If set to zero no
type of control is performed.
b40.5
Right limit-switch
.
Default=0. If set to 1 and the selected reference requires positive speed,
the reference will be forced to zero in accordance with the ramp set in Pr12. If set to zero no
control Is performed.
b40.6
Stop function
.
Default=0. If set to 1 the motor is stopped according to the ramp set in Pr12.
b40.7
Absolute/relative speed window selection
.
Default=0. If set to zero speed windows Pr14
Pr15 b41.1 will operate in relative mode, if set to 1 the speed windows will operate in
absolute mode.
b40.8
Analogue torque limit
.
Default=0. If set to 1, Pr22, i.e. auxiliary analogue input, will be
used to limit motor torque.
b40.9
Software enable
.
Default=1. If set to zero the drive cannot be started.
b40.10 Low voltage operation enable
.
Default=0. If at 1 the inrush current circuit will be
connected each time the drive is disabled, thus permitting rapid increases in power supply
voltage. When the drive is started the inrush current circuit will be connected before the
effective start-up of the power stage. This procedure causes a drive start-up delay of 120mS.
b40.11 Analogue output selector
.
Default=0. If set to 0 the analogue output will carry a signal
proportional to motor torque. If set to 1 it carries a value proportional to Pr38.
b40.12 Digital/analogue reference selector
.
Default=0. If set to 0 the analogue input is selected
as the main reference. If set to 1 the reference will be digital and, by means of 40.13, it can
be set for internal or external. If set for an external input, using b42.5 this can be set for
quadrature or frequency/direction.
b40.13 Internal or frequency reference selector
.
Default=0. If b40.12=1, b40.13 can be set to 0
to select internal reference, or to 1 to select the frequency input (encoder-in) which, in turn
can be configured as frequency/direction or quadrature signal using b42.5.
b40.14 Serial communication enable
.
Default=0. Set this parameter to 1 to enable serial comms.
b40.15
Reserved.
Must
remain on zero
.
b41.0
Overspeed
.
When the absolute motor speed value exceeds the value set in Pr13, b41.0 is
on 1, otherwise it is on 0.
