The reason for the step loss is those
The voltage instability in the high-speed operation causes the input current to fall short of the rated current, causing the output torque to fall and eventually to the step. 2 the speed setting is too high, the torque is not enough. 3) external resistance is too great. 4) the rate rises or falls too fast, causing the lost step.
the auxiliary power source is not suitable, and the auxiliary power supply should be 1.5-2 times the rated power supply of the driver, which is more serious than the imaginary mark The control part should be excluded from interference, away from the frequency converter, antistatic. The equipment can be ground to ground processing, prevent the inductive power, the signal line is done to block processing, set up the proper start frequency, and do well to add deceleration
Analysis of stepping and missing steps of stepping motor: Step 1: in the wrong type of motor, the inertia of the motor moment is not enough, or the inertia of the motion of the object exceeds the self-locking force of the motor, causing the lost step or the lost step 2: drive improper selection, form a complete set of drive current is small, affect the normal operation of motor, now on the market a lot of drive current virtual target, take a peak current when the rated current to fool consumers, drive type rated current should be greater than stepper motor 1.2 1.5 times rated current
