The steered wheel is in the 1
the configuration of the toggle switch is the one expected for a steered wheel
angle in the range 0 to 180 degrees.
The steered wheel is in the 4
the configuration of the toggle switch is the one expected for a steered wheel
angle in the range -180 to 0 degrees.
FEEDBACK SECTOR is compared with WHEEL ANGLE to raise the POSITION
ERROR alarm in case of mismatching (see 13.1.4).
4) FEEDBACK ENC
Voltage value with 2 decimal digit. Measurement (scaled in the range 0 to 5
Vdc) of the position of the feedback encoder connected to CNB#7 and CNB#8.
5) TEMPERATURE
Degrees. Temperature of the controller base plate.
6) MOTOR TEMPERATURE
Degrees. Temperature of the motor windings measured with the thermal sensor
inside the motor and connected to CNB#3.
7) FREQUENCY
Hertz value with 2 decimal digit. This is the frequency applied to the steering
motor.
8) SAT. FREQ HZ
Hertz value with 2 decimal digit. This is a real time magnetic flux measurement:
Vbattery/ SAT. FREQ HZ provides real time the linked flux in the motor. The flux
in the motor is modulated from 75% to 100% of the maximum flux.
The maximum flux is Vbattery/SET SAT FREQ.
The minimum flux is Vbattery/(1.33*SET SAT FREQ). When the motor is
loaded, SAT. FREQ HZ is equal to SET SAT FREQ; when the motor is
lightened the flux reduces and SAT. FREQ HZ increases up to 1.33*SET SAT
FREQ.
9) MOTOR VOLTAGE
It is a percentage. 100% means the sine waves in the motor have the maximum
PWM amplitude.
10) MOTOR CURRENT
Ampere value. Root Mean Square value of the line current in the motor.
11) ENC SPEED
Hertz value with 2 decimal digit. This is the speed of the motor measured with
the encoder on the motor shaft.
12) ENDSTROKE CW
Provides real time the active state (ON) or not of the CW toggle switch
(connected to CNA#3). It is On when CNA#3 is low (see 6.5).
13) ENDSTROKE ACW
Provides real time the active state (ON) or not of the CCW toggle switch
(connected to CNA#2). It is On when CNA#2 is low (see 6.5).
14) CW LIMIT LEVEL
When the maximum angle limitation via feedback sensors is enabled (option
