Acceleration Control
When driving the motor, acceleration control is needed to start paper feeding. When the motor is to be
driven at the maximum motor drive frequency that is calculated using equation (1), the motor may come
out of step under heavy load.
Drive the motor to the maximum driving speed that is calculated using equation (1), according to the
acceleration steps in
Table 3-5
.
The method for accelerating the motor is as follows;
1. Output start step (6580 (
μ
s)) for the time calculated using equation (1)
2. Output first step for the first acceleration step time
3. Output second step for the second acceleration step time
4. Output nth step for the nth step acceleration time
5. After outputting the time calculated using equation (1), the motor is driven at a constant speed.
The printer can print during acceleration.
