Legend: R: read; W: write; M: memory; K: key parameter.
Par. Description Range Def.
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.
[rpm]
Analogue reference offset. Expressed as a count of the
input converter.
[1=~0.3
M
First full scale of analogue reference. 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.
[rpm]
M
Second full scale of the analogue reference: If b40.0=0
and b40.12=0, the value of Pr7 will be equal to: Vin ⋅
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
[rpm]
M
Full scale of frequency reference: 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
[rpm]
M
Internal reference: If b40.12=1 and b40.13=0, Pr7 will be
equal to Pr5.
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
[rpm]
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.
[rpm]
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.

M
Deceleration ramp for positive speed: Positive speed
deceleration required by the motor via the speed reference is
internally limited so that to achieve an acceleration of 1000
rpm, Pr9 seconds are necessary.
