7.5.15 Operation as complementary modulation output function
The 120 degree excitation method is an inverter control method used for 3-phase brushless DC motors. The
complementary modulation output function can be used to realize this method. By using a complementary method,
braking can also be controlled. The complementary modulation output function sets three duty widths for one period
and generates 3-phase triangular wave modulation PWM output with added dead time (TOp and TOq). The
complementary modulation output function uses one period generation channel (channel 0), three duty generation
channels (channels 2, 4, and 6), and three dead time generation channels (channels 3, 5, and 7) (6-phase triangular
wave PWM output function). See 7.5.6 Operation as 6-phase triangular wave PWM output function for details of
the 6-phase triangular wave modulation PWM function.

outputs are modulated and output from the TOp and TOq pins when TMEp and TMEq are “1”. When TMEp and
TMEq are “0”, the real-time output setting value (TROp and TROq) will be output from the TOp and TOq pins.
levels of the TOp and TOq pins according to the settings of TOLp and TOLq of slave channels 2 to 7. (The default
levels are at low level when TOLp and TOLq are “0”, and at high level when TOLp and TOLq are “1”.)
3, 4 and 5, and 6 and 7 operate as pairs. The operation is as follows.
PWM is output from the TOq pin of a channel that is to be paired with the channel for which TROp is set to “1”.

The output is modulated in accordance with the TROp and TROq values corresponding to the TOp and TOq pins
Complementary modulation output is generated by using 6-phase triangular wave PWM, the TROp and TROq
The master channel operates in the interval timer mode and counts the periods.
TCRn of slave channel 1 operates in event counter mode and generates a real-time output trigger. The number of
When using this function, set the thinning of INTTM00 to odd numbers (1, 3, 5, …).
Slave channels 2, 4, 6 operate in up and down count mode, count the duty factor.
Slave channels 3, 5, 7 operate in one-count mode, count the dead time factor.
A 6-phase triangular wave PWM waveform with dead time is output by changing TOp and TOq by the count
Furthermore, modulation output can be controlled by manipulating TMEp and TMEq. The PWM and real-time
