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-hand stroke end
. 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-hand stroke end
. 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.
