The electrical discharge machining tool operates in the oscillation zone, solution:

1. Change the input signal frequency CP to avoid the oscillation zone.

2. Use a microstepping driver to reduce the step angle for smoother operation.

The electrical discharge machining tool is shaking and cannot run continuously, what should be done?

First, check if the connection between the winding of the electrical discharge machining tool and the driver is incorrect.

Check if the input pulse signal frequency is too high and if the frequency rise and fall design is unreasonable.

Under what circumstances is the offline signal FREE of the electrical discharge machining tool driver used?

When the offline signal FREE is at a low level, the current output from the driver to the motor is cut off, and the motor rotor is in a free state (offline state). In some automated devices, if the motor shaft needs to be rotated directly (manually) while the driver is powered, the FREE signal can be set to low to take the motor offline for manual operation or adjustment. After manual completion, the FREE signal can be set high to continue automatic control.

How to choose the power supply for the electrical discharge machining tool driver.

Determine the supply voltage of the driver, then determine the working current; the power supply current is generally determined based on the output phase current I of the driver. If a linear power supply is used, the power supply current can generally be taken as 1.1 to 1.3 times I; if a switching power supply is used, the power supply current can generally be taken as 1.5 to 2.0 times I.
