Pr 0 Motor speed: a read-only parameter expressed in rpm; the
Pr0 message is not ever displayed on the screen. Instead, the
message indicating the status of the converter is displayed.

Pr 2 First full scale of analogue reference: Unit = rpm,
range=±10000, default=3000. If b40.0=0 and b40.12=0, the
value of Pr7 will be equal to: Vin
⋅ Pr2 / 9.76 where Vin is
the voltage at the analogue input.

Pr 3
Second full scale of the analogue reference: Unit = rpm,
range=±10000, default=3000. If b40.0=0 and b40.12=0, the
value of Pr7 will be equal to: Vin
⋅ Pr2 / 9.76 where Vin is
the voltage at the analogue input.
If b42.0=1, b42.1=0, and b42.5=1, Pr3 is the speed of the
virtual axis.

Pr 4
Full scale of frequency reference: (connector X3). Unit =
rpm, range=±32767, default=3000. If b40.12=1 and
b40.13=1, the value of Pr7 will be the following:
If b42.5=0, Pr7 = Fin
⋅ Pr4 *2 / 2000000 (frequency/sign
signals)
If b42.5=1, Pr7 = Fin
⋅ Pr4 *2 / 500000 (quadrature
signals)
where Fin is the frequency present at the encoder input:
Fin=enc speed [Rpm] * enc pulses turn / 60

Pr 5 Internal reference: If b40.12=1 and b40.13=0, Pr7 will be
equal to Pr5.

Pr 6 Reserved speed reference (read-only): If b40.2=1, this
value is used as a reference for the speed regulator. The
active operating mode will write its speed request in
parameter Pr6.
±9000
[rpm]
0 R
Pr 7 Main reference (read-only): If b40.2=0 is used, Pr7 is the
reference for the speed regulator. In some operating modes
Pr7 can be used as a reference for other values
(torque/acceleration) and in these cases Pr7 will be
expressed in the most suitable unit of measurement.
±9000
[rpm]
R
Pr 8 Acceleration ramp for positive speed: Positive speed
acceleration required by the motor via the speed reference is
internally limited so that to achieve an acceleration of 1000
rpm, Pr8 seconds are necessary.
