TIMING DESCRIPTIONS AND DIAGRAMS
DEVICE FUNCTIONAL DESCRIPTION
Note:
P
n
=
n
This means: on the
n
th step, the motor indexed by
n
positions and is accelerating steadily at the maximum
allowed rate. This is critical because it also indicates the
minimum distance the motor must travel while decelerating to
a stop. For example, the
stopping distance
is also equal to
the current value of
n
.
The algorithm to drive the motor is similar to:
While the motor is stopped, wait until a command is
received.
Send index pulses to the motor at an ever-increasing rate,
according to the time steps in Table 13 until:
The maximum velocity is reached; at this point
the time intervals stop decreasing
or:
The distance remaining to travel is less than the
current index in the table. At this point, the
stopping distance is equal to the remaining
distance, ensuring it will stop at the required
position, the motor must begin decelerating.
An example of the table for a particular motor is provided
in Table 14. This motor’s maximum speed is 4800
microsteps/s (at 12 microsteps/degrees), and its maximum
acceleration is 54000 microsteps/s
2
. The table is quantized
to a 1 MHz clock.
