3.4.3 Precautions for Driving the Motor
(1)
Motor Current Control
When the motor speed decreases during printing because of the division drive method, the contents of
print data, or input data transfer speed, noise and overheating of the motor may occur due to over-
torque of the motor.
To prevent these symptoms from occurring, control the motor current as follows:
First, activate the motor with the 1st setting current in each motor drive step.
Change the activation current to the 2nd setting current after activating the motor with the 1st setting
current for T1.
T1 is defined from each period of the motor drive step and Vp voltage as follows:
How to define T1 (unit:
μ
s)
When Vp is under 7.2 V :
T1:
Compare the following two values and adopt the smaller one.
(Each period of the motor drive step - 500) and 925.9
When Vp is 7.2 V or more :
T1:
Compare the following two values and adopt the smaller one.
(Each period of the motor drive step - 500) and (1000000 / (3600 - Vp
