Description
DC BUS CURRENT
(A)
Ampere (1 A) Estimation of the DC current the inverter is drawing from
the battery.
BATTERY CHARGE
(A)
Percentage (1%) Estimation of the battery charge based on the battery
voltage.
MOTOR VOLTAGE
(A)
Percentage (1%) Theoretical phase- to- phase voltage to be applied at the
motor terminals, as a percentage of the supply voltage.
The actual applied voltage is changed by INDEX
OVERMOD. (see next item).
INDEX OVERMOD.
(A)
Percentage (1%) Correction applied to the motor-voltage set-point in order
to compensate for the actual battery voltage.
The actual motor voltage delivered is the product of
MOTOR VOLTAGE and INDEX OVEMOD.
FREQUENCY
(A)
Hertz (0.1 Hz) Frequency of the current sine-wave that the inverter is
supplying to the motor.
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 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
