How does the step motor start?
LOCK is a signal that a signal error causes the entire program to be stuck, equivalent to a valve. I don't know exactly. If is the printer display error, it may be bought your driver do not match, drive is divided into single pulse and double pulse drive, your is double pulse mode, you can find technical personnel change the drive to try single pulse mode, pay attention to the voltage and current of driving
Load, acceleration time, voltage and current, drive. In general internal procedures are in place to make good printers, country can rule out the possibility of acceleration time, voltage and current is relative to drive, if your driver and motor can't match each other, will be very easy to burn, big load can lead to burn, not only will be blocked, so the load side also can be ruled out, so I suggest you check the drive and motor matches. As for the load large motor can't start the problem, the voltage and current are related, the influence of the current is large, but current if will cause the whole machine heating, I don't recommend increase current. The most direct method is to change the motor of a big torque, because the price is also very little, convenient and quick.
The stepping motor moves from rest to a certain speed, which requires a gradual acceleration, otherwise the phenomenon of "missing step" occurs. The larger the power, the greater the inertia, the longer it takes to get started. As a result, the pulse frequency of the output of the controller should be accelerated from 0 to the required value of the actual revolution. In order to accelerate the pulse speed, the power and load characteristics of the motor should be considered, the time constant. It can also be determined through actual debugging.
How to speak? The step motor starts with four aspects: load, acceleration time, voltage and current, drive. In general internal procedures are in place to make good printers, country can rule out the possibility of acceleration time, voltage and current is relative to drive, if your driver and motor can't match each other, will be very easy to burn, big load can lead to burn, not only will be blocked, so the load side also can be ruled out, so I suggest you check the drive and motor matches. As for the load large motor can't start the problem, the voltage and current are related, the influence of the current is large, but current if will cause the whole machine heating, I don't recommend increase current.
