DUAL AC2 SLAVE TRACTION UNIT
MOTOR VOLTAGE:
voltage supplied to the motor by the inverter; it is expressed as a
percentage of the full voltage (which depends on the battery voltage).
FREQUENCY:
frequency of the voltage and current supplied to the motor.
ENCODER:
speed of the motor, expressed in the same unit as the frequency; this
information comes from the speed sensor.
SLIP VALUE:
difference between the rotating field frequency and the motor shaft
frequency (measured by the encoder)
CURRENT RMS:
Root Mean Square value of the motor current.
TEMPERATURE:
temperature measured on the aluminum heat sink holding the MOSFET
devices.
SEAT SWITCH:
state of the Seat Microswitch digital input.
ON / +VB* = active input, closed switch.
OFF / GND = non-active input, open switch.
FORWARD SWITCH:
state of the Forward direction digital input FW.
ON / +VB* = active input, closed switch.
OFF / GND = non-active input, open switch.
BACKWARD SWITCH:
state of the Reverse direction digital input BW.
ON / +VB* = active input, closed switch.
OFF / GND = non-active input, open switch.
ENABLE SWITCH:
state of the Enable digital input:
ON / +VB* = active input, closed switch.
OFF / GND = non-active input, open switch.
VOLTAGE BOOSTER:
voltage booster supplied to the motor in load condition; it is expressed
as a percentage of the full voltage.
BATTERY VOLTAGE:
level of battery voltage measured with the key switch ON.
* = The console shows “ + VB “, but the real voltage is +5V
