Description
MEASURED SPEED
(A)
Hertz (0.1 Hz) Motor speed measured through the encoder and
expressed in the same unit of FREQUENCY (Hz).
SLIP VALUE
(A)
Hertz (0.01 Hz) Motor slip, i.e. difference between the current frequency
and the motor speed (in Hz).
CURRENT RMS
(A)
Ampere (1 A) Root-mean-square value of the line current supplied to
the motor.

2
IMAX LIM. TRA
(A)
Ampere (1 A) Instantaneous value of the maximum current the inverter
can apply to the motor to satisfy a traction request. The
value is evaluated basing on actual conditions (inverter
temperature, motor temperature, etc…).
IMAX LIM. BRK
(A)
Ampere (1 A) Instantaneous value of the maximum current the inverter
can apply to the motor to satisfy a braking request. The
value is evaluated basing on actual conditions (inverter
temperature, motor temperature, etc…).
ID FILTERED RMS
(A)
Ampere (1 A) Projection of the current vector on the d-axis, expressed
in root-mean-square Ampere.
IQ FILTERED RMS
(A)
Ampere (1 A) Projection of the current vector on the q-axis, expressed
in root-mean-square Ampere.
IQIMAX LIM. TRA
(A)
Ampere (1 A) Maximum value of the q-axis current component,
according to traction-related settings, expressed in
root-mean-square Ampere.
IQIMAX LIM. BRK
(A)
Ampere (1 A) Maximum value of the q-axis current component,
according to braking-related settings, expressed in
root-mean-square Ampere.
FLAGS LIMITATION
(A)
ON, OFF Flag for any current limitation being active, for example
thermal current cutback, maximum current reached, etc. .
MOT. POWER WATT
(A)
Watt (1 W) Estimation of the power supplied to the motor.
STATOR FLUX MWB
(A)
10
-3
Weber (0.1 mWb) Estimation of the motor magnetic flux.
MOTION TORQUE NM
(A)
Newton Meter (0.1 Nm) Estimation of the motor torque.
STEER ANGLE
(T, TM)
Degrees (1°) Current steering-wheel angle. When the steering is
straight ahead STEER ANGLE is zero.
