The servo driver is an important part of the CNC cutting machine. Its role is to control the running speed of the machine and ensure the cutting accuracy of the CNC cutting machine. However, the driver sometimes appears upside down? What causes this? How can we solve it? Wuhan tyrants to answer for you one by one:
cause:
1, the speed signal is not stable, such as speed measuring devices;
2, due to poor contact terminals, resulting in speed control signal instability or interference.
3. When the turbulence occurs in the moment of transition from the forward movement to the reverse movement, it is generally caused by the reverse clearance of the feed chain or the excessive gain of the servo system.
Servo turbulence fault elimination method is to check possible points of failure in order, find the cause of the fault and take appropriate measures. The solution is as follows:
1. Whether the grounding terminal of the motor and the grounding PE terminal of the driver is well connected.
Second, the connection cable and plug have bad contact.
Third, the driver's grounding PE terminal is grounded.
4. If the connection cable is long, the pressure drop of the movie on the cable may be too large. Try changing the 5V and 0V power supplies of the encoder with multiple core wires.
5. The shielded wire of the connecting cable is soldered. Do not connect the connecting cable with a strong cable and try to change the connecting cable trace.
