Page – 45/75
Duty cycle of the PWM from the second set-point sensor.
5) SP POS COMMAND
Unit: degrees.
Angle the E-steering is trying to perform at the steered wheel.
6) STEERED
ANGLE
Unit: degrees.
Angle of the steered wheel.
7) CENTER WHEEL SW
ON/OFF
Status of the home switch.
8) SAFETY STEER OUT
ON/OFF
Status of the safety steer output.
9) SINUS
CNA3
Unit: mV.
Sine signal of the motor feedback converted in voltage (5 V correspond to the
full amplitude).
10) COSINE CNA4
Unit: mV.
Cosine signal of the motor feedback converted in voltage (5 V correspond to the
full amplitude).
11) FEEDBACK ENC.
Unit: Voltage 0 through 5000 mV.
Value of the encoder counting scaled in the range 2500 mV ± 2500 mV
corresponding to a 0° ± 180° of the steered wheel. A steered wheel angle in the
range 0 ± 90° corresponds to a FEEDBACK ENC of 2500 mV ± 1250 mV (i.e.
from 1250 mV to 3750 mV).
Adjustment SET STEER 0-POS must be set in order the encoder counting is
null (and FEEDBACK ENC is 2500 mV) when the steered wheel is really
straight ahead.
12) ENC COUNTING
Unit: pulses.
Counts of the encoder (this is a virtual encoder digitally derived basing on the
information from the analog feedback sensor).
Adjustment SET STEER 0-POS must be set in order the encoder counting is
null when the steered wheel is really straight ahead.
13) ENC SPEED
Units: Hertz.
Speed of the motor encoder (this is a virtual encoder digitally derived basing on
the information from the analog feedback sensor).
14) FREQUENCY
Units: Hertz.
Frequency applied to the steering motor.
15) MOTOR VOLTAGE
