MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
22
The motor is stepped by providing index commands at
intervals. The time between steps defines the motor velocity,
and the changing time defines the motor acceleration.
The state machine uses a table defining the allowed time
steps, including the maximum velocity. A useful side effect of
the table is, it also allows the direct determination of the position
the velocity should reduce to allow the motor to stop at the
desired position.
The motor equations of motion are generated as follows:
The units of position are steps, and velocity and acceleration
are in steps/second, and steps/second.
From an initial position of 0, with an initial velocity u,the
motor position, s at a time t is:
For unit steps, the time between steps is:
This defines the time increment between steps when the
motor is initially travelling at a velocity . In the ROM, this time
is quantized to multiples of the system clock by rounding
upwards, ensuring the acceleration never exceeds the allowed
value. The actual velocity and acceleration is calculated from
the time step actually used.
