Each period must start with the Motor Off state. As a general rule, sequence
times 1 to 4 only describe the time response when there is an edge transi-
tion from LOW to HIGH. If a period duration that is shorter than the LOW
sequence time is selected, the motor will stop. Period durations that are lon-
ger than the start time for the HIGH sequence will control the motor power,
with the state remaining for the rest of the period duration.
Enable
The enable signal is activated with motor control object 0x20E7, bit 0. The
output sequence will not be applied at the M+/M- motor output until this
enable signal is active. Once the enable signal has been activated, the rele-
vant parameters will change directly as required for the output signal for the
motor, M+, M-.
Defining the period duration
The period duration is determined based on the time value stored in object
0x20E4 and the system clock frequency (32 MHz).
In turn, the period duration is used to determine the fundamental frequency.
Period duration = Time value register entry (16-bit)
