Description
Volt
KEY voltage Pin A3 value measured in real time.
(0.1V)
Volt
Battery voltage measured in real time across the DC-bus.
(0.1V)
Ampere
Estimation of the battery current based on the working point.
(1 A)
Percentage
Estimation of the battery charge based on the battery voltage.
(1%)
Percentage Estimation of the battery charge based on the data coming from the Delta Q
(1%) Charger. It is updated only at the startup. 0 if the charger is not present.
Theoretical phase- to- phase voltage to be applied at the
Percentage
(1%)
motor terminals, as a percentage of the supply voltage.
Percentage correction applied to the motor-voltage set-point in order to
(1%) compensate for the actual battery voltage.
Hertz Frequency of the current sine-wave that the inverter is
(0.1 Hz) supplying to the motor.
Hertz Motor speed measured through the encoder and expressed
(0.1 Hz) in the same unit of FREQUENCY (Hz). (Master Motor)
Hertz Motor speed measured through the encoder and expressed
(0.1 Hz) in the same unit of FREQUENCY (Hz). (Master Motor)
Hertz Motor slip, i.e. difference between the current frequency and
(0.1 Hz) the motor speed (in Hz).
Ampere Root-mean-square value of the line current supplied to the
(1 A) master (right) motor.
Ampere Root-mean-square value of the line current supplied to the
(1 A) slave (left) motor.
Instantaneous values of the maximum current the inverter
Ampere can apply to the motor to satisfy respectively a traction or
(1 A) braking request. The value is evaluated basing on the realtime
conditions (inverter temperature, motor temperature, etc.).
Instantaneous values of the maximum current the inverter
Ampere can apply to the motor to satisfy respectively a traction or
(1 A) braking request. The value is evaluated basing on the realtime
conditions (inverter temperature, motor temperature, etc.).
Ampere Projections of the current vector respectively on the d- or qaxis,
(1 A) expressed in root-mean-square Ampere.
Ampere Projections of the current vector respectively on the d- or qaxis,
(1 A) expressed in root-mean-square Ampere.
Master motor: instantaneous value of the maximum current the inverter can
Ampere
apply to the motor to satisfy a traction request. The value is evaluated basing on
(1 A)
the real-time conditions (inverter temperature, motor temperature, etc.).
