13. Example of AC Synchronous Motor (Brushless DC Motor) Drive Waveform Output
Rev.4.00 Mar. 27, 2008 Page 306 of 882
REJ09B0108-0400
In complementary PWM mode, a brushless DC motor can easily be controlled using the timer
gate control register (TGCR). Figures 11.50 to 11.53 show examples of brushless DC motor
drive waveforms created using TGCR.
When output phase switching for a 3-phase brushless DC motor is performed by means of
external signals detected with a Hall element, etc., clear the FB bit in TGCR to 0. In this case,
the external signals indicating the polarity position are input to channel 0 timer input pins
TIOC0A, TIOC0B, and TIOC0C (set with PFC). When an edge is detected at pin TIOC0A,
TIOC0B, or TIOC0C, the output on/off state is switched automatically.
When the FB bit is 1, the output on/off state is switched when the UF, VF, or WF bit in TGCR
is cleared to 0 or set to 1.
The drive waveforms are output from the complementary PWM mode 6-phase output pins.
With this 6-phase output, in the case of on output, it is possible to use complementary PWM
mode output and perform chopping output by setting the N bit or P bit to 1. When the N bit or
P bit is 0, level output is selected.
The 6-phase output active level (on output level) can be set with the OLSN and OLSP bits in
the timer output control register (TOCR) regardless of the setting of the N and P bits.
