MOTOR CONTROLLER (Cont’d)
Sensor Mode
In sensor mode, the rotor position information is
given to the peripheral by means of logical data on
the three inputs MCIA, MCIB and MCIC.
For each step one of these three inputs is selected
(IS[1:0] bits in register MPHST) in order to detect
the Z event.
In this case Demagnetization has no meaning and
the relevant features such as the special PWM
configuration, DS or DH management, 20-s filter;
are not available (see Table 14).
For this configuration the rotor detection doesn’t
need a particular phase configuration to validate
the measurement and a Z event can be read from
any detection window. A fixed sampling frequency
(800 kHz) is used, that means the Z event and po-
sition sensoring is more precise than it is in sen-
sorless mode.
The minimum off time for current control PWM is
also reduced to 1.25
s.
Procedure for reading sensor inputs in Direct
Access mode: In Direct Access mode, the periph-
eral clock is disabled as shown in Table 25. As the
data present on the selected input is synchronized
by a 800 kHz clock, the sensor can’t be read di-
rectly (the value is latched). To read the sensor
data the following steps have to be performed:
1. Select the appropriate MCIx input pin by means
of the IS[1:0] bits in the MPHST register
2. Switch from direct access mode to indirect
access mode in order to latch the sensor data
(DAC bit in MCRA register).
3. Switch back to direct access mode.
4. Read the comparator output (HST bit in the
MIMR register)
