7.3 TESTER function
The TESTER function gives real-time feedbacks about the state of controller, motor
and command devices. It is possible to know the state (active/inactive) of the digital
I/Os, the voltage value of the analog inputs and the state of the main variables used
for the motor and hydraulics control.
In the following tables, “Parameter” columns also report between brackets lists of
the controller types where each parameter is available.
Controller types are coded as:
A =
All controller types
T =
Traction controllers (in single motor applications)
TM =
Traction master controllers (in multiple motor applications)
TS =
Traction supervisor controllers (in multiple motor applications)
P =
AC pump controllers
CO =
CANopen controllers
N =
none
7.3.1 Master microcontroller
The following table lists the master microcontroller data that can be monitored
through the TESTER function.

Description
KEY VOLTAGE
(A)
Volt (0.1 V) Key voltage measured in real time.
BATTERY VOLTAGE
(A)
Volt (0.1 V) Battery voltage measured in real time (across the DC
bus).
DC BUS CURRENT
(A)
Ampere (1 A) Estimation of the DC current the inverter is drawing from
the battery.
BATTERY CHARGE
(A)
Percentage (1%) Residual battery charge as percentage of the full charge.
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.
