FEEDBACK DEVICE, cont’d
NAME
ALLOWABLE
RANGE RAW DATA DESCRIPTION
• Below is requirement for quadrature Encoder PPR(pulse per revolution)
due to internal RC lter circuit and different installation of encoder, the
max allowed input frequency is 20KHz.
Channel A
Channel B
360° electrical (1 cycle)
> 50 µs
180° ±18°
90° ±30°
1. = If the encoder is installed before the motor gearbox(attach to the steer
motor rotor).
Encoder Single Pulse Period = 60*10
6
/(Max Steer Motor RPM*Encoder
PPR) should > 50us(20KHz)
Example: Max Steer Motor RPM = 3000.
60 * 10
6
/ (3000 * Encoder PPR) > 50
Encoder PPR < 400
We recommend encoder PPR > 8 to avoid possible sampling error which
will lead to poor steering(following) accuracy.
2. = If the encoder is installed after the motor gearbox.
Encoder Single Pulse Period = Gearbox Ratio*60*10
6
/(Max Steer Motor
RPM*Encoder PPR) should > 50us.
Example: Max Steer Motor RPM = 3000.
Steer Motor Gearbox Ratio = 40:1
40 * 60 * 10
6
/ (3000 * Encoder PPR) > 50
Encoder PPR < 16000
We recommend encoder PPR > 8*40 to avoid possible sampling error
which will lead to poor steering (following) accuracy.
+5V Supply 2 (J3-11)
Position Analog 2 (Redundant)
Position Analog 1 (Primary)
Position Analog Feedback
I/O GND
2 = None. No supervisory position feedback device is connected. Only a
single position feedback device (the primary) is used.
This option is available only for the Supervision Feedback Device
parameter.
Using this setting may make the system noncompliant with EN
13849, and may cause a higher probability of dangerous failure,
and must be evaluated by the OEM.
When the Supervision Feedback Device is set to 2, wheel position
supervision is disabled. This option is provided to allow systems not
compliant with EN 13849 to be set up without having to supply connections
to the supervisory inputs from the single primary feedback device.
