Revolving speed is 900 revs/min, then error amount is -600 revs/min.
Step 306: the rotation distance of the first motor is read based on the dial sensor.
When code-disc often turns over a graduation mark, sensor can all generate corresponding level jump, and control module can root
The graduation mark that code-disc turns over is read according to level jump, finally by the distance that can be calculated code-disc and turn over.
Step 308: when the rotation distance of the first motor reaches pre-determined distance, the control module, which sends to shut down, to be referred to
It enables to the motor drive module, so that the motor drive module control first motor is out of service.
Pre-determined distance refers to needing the paper feed distance of the print paper controlled, which can be system and set in advance
It sets, the operational order that can also be inputted according to host computer is arranged.When first motor driving paper advance mechanism reaches pre-determined distance, control
Molding block control first motor stops operating, to carry out next step printing.
The control method of the printing device provided through this embodiment can make first motor in driving paper advance mechanism luck
Row stops at accurate cut paper position in stable revolving speed, convenient for control module control first motor, and then promotes printing device
Paper feed distance control accuracy, make print paper cutting it is more neat, promoted printing effect.
In one embodiment, the printing device further includes the second motor, second motor and the motor driven
Module electrical connection.The control method of the printing device further include: cutting instruction is sent to the motor based on the control module
Drive module, so that the motor drive module drives second motor operation；When the paper cutting mechanism completes cutter
After work, it is out of service that the control module controls second motor.
Wherein, the second motor refers to the motor for driving paper cutting mechanism to run, and the shaft of the second motor connects cut paper
Mechanism, paper cutting mechanism movement is driven when the rotation of the shaft of the second motor, and the cutting instruction is used to indicate second motor
Drive paper cutting mechanism work.For example, the paper cutting mechanism is cutter, and after paper advance mechanism advance fixed range, control module control
Cutter carries out cutting operation, with the print paper needed.
Optionally, after second motor is out of service, the control module sends the second rotary speed instruction to the electricity
Machine drive module, so that the motor drive module drives the first motor operation.Wherein, the second rotary speed instruction is for referring to
Show that first motor is run by second direction to the second revolving speed, second direction be with first party in the opposite direction.
Further, the actual speed of the first motor is obtained, and between the actual speed and the second revolving speed
Error amount, the control module adjusts the speed algorithm according to the error amount combination PID and adjusts the running speed of the first motor,
So that the running speed of the first motor approaches second revolving speed.When the rotation distance of the first motor reaches default
Apart from when, the control module sends halt instruction to the motor drive module, so that the motor drive module controls
The first motor is out of service.
