2.1 Motor Driving Frequency

1) To drive the motor, it is recommended to rush-drive the last phase (a), then slow up as shown in
Table 2.1.1, and drive the motor with a constant speed driving (c).
2) To stop the motor, do not slow down. Hold the last phase with one step at rush-driving (d) (65 ms)
so that the motor stops.
3) The problem of shading during printing can be caused by voltage fluctuation or some print patterns.
4) To avoid damage to the motor from high temperature, after the motor is driven continuously driven
for t seconds, set a stopping period for over 3t seconds, where t is less than 60 seconds.
