BINARY PARAMETERS
Binary parameter Pb40 can either be read or programmed, bit by bit, and stored in the
memory. Binary parameter Pb41 provides information regarding system status. Parameters
Pb42 and Pb99 can be read or programmed bit by bit and stored.
b40.0 Selection of 1st or 2nd speed reference full scale value. Default=0. If set to 0 Pr2 is
used to standardise the analog reference, if set to 1 parameter Pr3 is used.
b40.1 Activation of algorithm for vibration suppression at 0 rpm. Default=0. Set to 1 to
activate the algorithm.
b40.2 User/reserved reference selection. 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 adopted. Default is 0.
b40.3 Reference hold. Default=0. If set to 1 the reference will not be updated so the motor
will not follow input reference modifications. If set to zero the reference will follow
variations in the reference input.
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 Pr
12. 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
Pr 12. 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 Pr 12.
b40.7 Absolute/relative speed window selection. Default=0. If set to 0 speed windows Pr
14 Pr 15 b 41.1 will operate in relative mode, if set to 1 the speed windows will
operate in absolute mode.
b40.8 Analog torque limit. Default=0. If set to 1, Pr 22, i.e. auxiliary analogue input, will
be used to limit motor torque.
b40.9 Software enable. Default=1. Of set to 0 the drive cannot be started.
b40.11 Auxiliary analog 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 Pr 38.
b40.12 Digital/analog reference selection. 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 b40.13, it can be selected between parameter Pr4 or parameter Pr5.
b40.13 Internal reference Pr5 or frequency reference Pr4 selector. Default=0. If
b40.12=1, b40.13 serves to select the internal reference when set to 0, and the
frequency input reference (encoder-in) when set to 1; the frequency input, in turn, can
be configured as frequency/direction or quadrature signal by means of b42.5.
b40.14 Serial communication enable. Default=0. Set this parameter to 1 to enable serial
comms.
b40.15 Reserved. Must always be set to 0.
b41.0 Overspeed. When the absolute motor speed value exceeds the value set in Pr 13, b
41.0 is on 1, otherwise it is on 0.
b41.1 At speed. With b40.7=0 if the speed difference between motor and reference is lower
than Pr 14 and higher than Pr 15, b41.1 will be 1, otherwise it will be 0. With
b40.7=1, if motor speed is lower than Pr 14 and higher than Pr 15, b41.1 will be 1,
otherwise it will be 0.
b41.2 Zero speed. If motor speed (Pr0) is zero rpm, b41.2=1, otherwise b41.2=0.
