interface board,; secondly, if the interface board and 50-pin cable are normal, then user
should check the power supply of the motor drivers.
3)
If debugged all above parts, but the machine still not move, then the mechanical parts
should be checked.
11. It is normal to the move from one position to another position, but when return from that
position to the original position is not normal
Mechanical assembly problem, guide screw may be not installed well.
12. Motor moving direction is wrong
1)
Exchange A+&A- or B+&B- cable of the stepper motor
2)
Change motor direction mask (not recommend)
13. The machine vibrates when moves in arc or two-axis linkage movement
1)
Check whether the machine is placed horizontally
2)
Check if the coupling units loose or not.
3)
Increasing the “start speed”, avoid the resonance point.
PS7.3 Electrical components and wiring problem
1.
A single axis or multi axis can only in one direction after machine power on
1)
There is something wrong with the connecting between the interface board and motor
driver common anode end, check the connection.
2)
Interface board is broken. Replace the interface board.
3)
The motor driver is broken. Replace the driver.
4)
Measure the direction voltage of that axis with a multimeter. Check if the direction is
correct.
2.
One axis motor does not move after handle power up
1)
Pulse cable and direction cable connect oppositely
，
adjust connection sequence..
2)
5V common anode end of the motor driver disconnected, check the connection.
3)
The motor driver is broken (Performance as the motor moves when push it by hand), change
a new one.
4)
The interface chip of the interface board is broken, no pulse signal output.
