What does Teana 2.0 fault code p 1777 mean?

If the stepper motor of the gearbox is always in a free state, the MF signal is normal. The solution to this situation is to adjust the MF signal circuit.

Causes and solutions of stepping motor faults;

1, the stepping motor is out of synchronization. At this time, the user will see if the shielded wire is loose and grounded, and see if the subdivision setting is correct. If the current is small, the current can be increased to solve this problem.

2. When the motor alarm indicator lights up, in this case, the user needs to check the voltage and power supply. Another possibility is that the stepper motor driver is damaged and the user needs to replace it with a new one.

3. There is an error in the rotation direction of the motor. In this case, there is probably something wrong with the wire. If the problem of wiring error is eliminated, it is that the motor wire is broken or the signal may be disturbed, and the user needs to eliminate this interference problem.

4. The power light can be turned on normally. TM light is off or on all the time. At this time, the signal circuit may be connected incorrectly, or the driver selection is wrong. ?

Extended data:

Precautions for stepping motor:

1. The stepping motor is used in low-speed situations-the speed per minute does not exceed 1000 rpm (0.9 degrees 6666PPS), and it is best to use it between 1000-3000PPS(0.9 degrees). Here, it can run through the reducer, with high working efficiency and low noise.

2. It is best not to use full stepping state for stepping motor, because full stepping state has great vibration.

3. When the motor is under high speed or large inertia load, it is generally not started at the working speed, but gradually increases the frequency and speed, which can reduce the noise and improve the positioning accuracy of shutdown.

4. The motor should not work in the vibration area. If necessary, it can be solved by changing the voltage and current or adding some damping.
