Unit of measure
(resolution)
Battery voltage measured in real time across the DC-bus.
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).
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 of the current sine-wave that the inverter is
supplying to the motor.
Motor 1 speed measured through the encoder and
expressed in the same unit of FREQUENCY (Hz).
Motor 2 speed measured through the encoder and
expressed in the same unit of FREQUENCY (Hz).
Motor slip, i.e. difference between the current frequency
and the motor speed (in Hz).
Root-mean-square value of the line current supplied to the
motor 1.
Root-mean-square value of the line current supplied to the
motor 2.
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.).
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.).
Projection of the current vector on the d-axis, expressed in
root-mean-square Ampere.
Projection of the current vector on the q-axis, expressed in
root-mean-square Ampere.
