Fourth, there are several reasons that the motor will not turn:
1. The overload is blocked (the motor has a howling sound at this time)
2. Is the motor offline?
3. Does the control system have a pulse signal to the stepper motor driver, and there is a problem with the wiring.
4, stepper motor jitter, can not run continuously, how to do?
In this case, first check if the winding of the motor is connected to the driver.
Check if the frequency of the input pulse signal is too high, and whether the design of the lifting frequency is unreasonable.
5. Under what circumstances is the offline signal FREE of the hybrid stepper motor driver generally used?
When the offline signal FREE is low, 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 automation equipment, if the drive is not powered
By directly turning the motor shaft (manual mode), the FREE signal can be set low, the motor can be taken offline, and manually operated or adjusted. After manual completion, set the FREE signal high to continue automatic control. 6, how to choose the stepper motor driver power supply?
Determine the supply voltage of the driver and then determine the operating current; the supply current is generally determined by the output phase current I of the driver. If using a linear power supply,
The power supply current can generally take 1.1 to 1.3 times of I; if a switching power supply is used, the power supply current can generally be
Take 1.5 to 2.0 times of I.
