Step motor drive, static current setting, what is the difference between setting ON or OFF?
OFF state can reduce electrical heating, but "brake" function is not strong, the motor rotation shaft torque under the action of outside the possibility of larger, severe cases can lead to Angle control error; ON state electrical opportunity heat, the temperature increase is permitted range. The "brake" effect is better than the former, which is suitable for high precision Angle control.
This is the automatic half flow function called stepping motor. Static refers to the operation of the motor when the motor is not running. In practice, it is judged by judging the impulse signals that are driven by the upper machine. Typically, the pulse stops the actual value of 100ms or 1-2s by halving or subtracting the set value of the stop state. When set to ON, turn ON this feature. Can reduce electric motor and drive heat, prolong service life, improve product reliability and so on.
Stepper motors are mostly used constant current control, the motor is not running, winding through the setting of current, still can cause motor calorific particularly severe, if it is a horizontal axis, can flow through a half way, reduce the motor to stop running current, reduce energy consumption and fever, if it is a vertical axis to consider to keep the torque of motor output to choose whether to half the size of the flow. The na control EZM series drive, the user can according to the size of the need to set a flow and flow into the half time, can minimize the fever of the machine.
