8.9 Tester: description of the function
The most important input or output signals can be measured in real time using
the TESTER function of the console. The Console acts as a multimeter able to
read voltage, current and temperature. In the following chapter a list of relative
measurements for different configurations.
8.9.1 "Dualac2" and "Dualac2 Power" - Master
1) MOTOR VOLTAGE
This is the voltage supplied to the motor by the inverter; it is expressed as a
percentage of the full voltage (which depends of the battery voltage).
2) FREQUENCY
This is the frequency of the voltage and current supplied to the motor.
3) ENCODER
This is the speed of the motor, expressed in the same unit of the frequency;
this information comes from the speed sensor.
4) SLIP VALUE
This is the difference of speed between the rotating field and the shaft of the
motor, expressed in the same unit of the frequency.
5) CURRENT RMS
Root Mean Square value of the motor current.
6) TEMPERATURE
The temperature measured on the aluminium heat sink holding the MOSFET
devices.
7) TEMPERATURE #1
This is the temperature of the right motor; if the option is programmed "None"
(see chapter 8.4.a) it shows 0°.
8) TEMPERATURE #2
This is the temperature of the left motor; if the option is programmed "None"
(see chapter 8.4.a) it shows 0°.
9) ACCELERATOR
The voltage of the accelerator potentiometer's wiper (CPOT). The voltage
level is shown on the Left Hand Side of the Console Display and the value in
percentage is shown on the Right Hand Side.
10) STEER ANGLE
This is the indication of the angular position of the steered wheel.
11) INTERNAL WHEEL CUTBACK
This is the indication of the speed reduction applied to the internal wheel; in
other words, it shows the ratio of the two speeds.
12) FORWARD SWITCH
The level of the Forward direction digital input FW.
- ON / +VB = input active, switch closed.
- OFF / GND = input non active, switch open.
13) BACKWARD SWITCH
The level of the Reverse direction digital input BW.
- ON / +VB = input active, switch closed.
- OFF / GND = input non active, switch open.
14) ENABLE SWITCH
The level of the Enable digital input:
- ON / +VB = input active, switch closed.
- OFF / GND = input non active, switch open.
