Command Description

CA[10] Resolver or Analog Halls offset – the value of the analog sensor readout

at the electrical zero of the motor

CA[11] Offset for the A (sine) channel of the Analog Encoder, Resolver, Analog

Halls or Absolute Coarse/Fine Encoder(fine mode). The offset is given in

ADC units in the range of [-4500…4500].

CA[12] Offset for the B (cosine) channel of the Analog Encoder, Resolver, Analog

Halls or Absolute Coarse/Fine Encoder(fine mode). The offset is given in

ADC units in the range of [-4500…4500].

CA[13] Relative gain of the A (sine) channel of the Analog Encoder, Resolver,

Analog Halls or Absolute Coarse/Fine Encoder(fine mode) with respect to

the B (cosine) channel in the range of [20000…40000].

Table 3-4: CA - Analog Feedback Scaling

Command Description

CA[16] Feedback direction:

0: Use feedback reading as is

1: Invert the direction of the feedback reading

Changing CA[16] does not affect the present position count.

Direction changes only when counting future feedback pulses.

CA[17] Commutation method.

0: Use only Hall sensors. The electrical angle resolution will be 60

electrical degrees.

1: Hall sensors are used together with a high resolution sensor. On the

first Hall sensor transition, the exact electrical angle is locked and

commutation continues by position sensor increments. The Hall

sensors continue to monitor commutation correctness – refer to

PN[1]

2: Halls are sole commutation source. On high speeds, use time-based

interpolation for smoothing the electrical angle estimate.

3: Commutation initializes by auto phasing, in the oscillation method

(see CA[15],CA[24],CA[26],CA[27]). After initialization,

commutation continues by position sensor increments.

4: Commutation initializes by auto phasing, in the magnetic saturation

method (see CA[15],CA[24],CA[26],CA[27]). After initialization,

commutation continues by position sensor increments.
