How do you change the direction of the step motor
Because of problems before control technology, the controller needs to two-way pulse signal to control the step motor rotation direction, in this way closer to the ordinary motor control mode. Has had less use, mainly is two way control pulse and pulse costs all the way, many pulse need to increase the cost of all the way, now very simple control stepping motor and reversing.
The step electrical and electrical machinery is controlled by the pulse frequency. There are two modes of control, single pulse mode. This is the high and low level control, high level control in one direction, low level control in the other direction. This is also the current way of controlling stepping motors.
Three-phase stepper motor can change direction in line, if it is bad five phase is changed, can find a row selector switch power amplifier module, there is a change of phase sequence, this according to the manual operation, you can also try one by one, not dial back and try again next, until the direction of change.
