Par. Description Field Range Def. Res.
Pr0
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.
R ± 15.000

0 1 rpm
Pr7 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.
R ±9000

Pr13 Overspeed limit. If the absolute value of
the motor speed exceeds the value set in
Pr13, b41.0 will be =1, Otherwise, it will be
= 0.

Pr14 High speed limit. If b40.7=0 and if the
difference of the speed of the motor and the
reference is less than Pr14 and greater than
Pr15, b41.1 will be = 1. Otherwise, it will
be 0. If b40.7 = 1 and if the motor speed is
less than Pr14 and greater than Pr15, b41.1
will be =1. Otherwise, it will be =0.

Pr15 Low speed limit. If b40.7=0 and if the
difference of the speed of the motor and the
reference is less than Pr14 and greater than
Pr15, b41.1 will be =1. Otherwise, it will be
=0. If b40.7=1 and if the motor speed is less
than Pr14 and greater than Pr15, b41.1 will
be =1. Otherwise, it will be =0.

Pr18 Band width limiter. Pr18 is used to set the
time constant of a first order filter placed on
the digital signal of the torque request. The
frequency of the filter cut will be:
1240/Pr18 Hertz.

Pr19 Peak torque. This is the maximum torque
that the converter can supply to the motor.
It is expressed as a percentage of the peak
current of the motor multiplies to motor
constant torque.
