I.Hotel electronic door locksHow to reverse the motor's operation?
Methods for handling the rotational direction of motors in different working environments:
1、Input for single pulse operation
The control switch for the signal module should be set to the "single pulse" position, and the motor will rotate when a pulse output is detected. Changing the high and low levels of the direction signal will change the direction of motor rotation.
2、When using dual pulse input
The control switch for the signal module should be set to the dual pulse position. When a positive pulse is sent, the motor rotates in the forward direction; when a negative pulse is sent, the motor rotates in the reverse direction. However, it is important to note that both positive and negative pulses cannot be sent simultaneously.
For cases where the motor's running direction is opposite to the required direction, the following two methods are recommended:
One approach is to modify the control system's directional signals.
Another method involves changing the direction by adjusting the wiring of the step motor.
Specific procedures are as follows:
1、For two-phase motors, simply swap the connection of one of the motor wires to the stepper motor driver, for example, swapping A+ and A-.
2. For three-phase motors, it is not possible to swap the wires of one phase; instead, the wires of two phases should be swapped in sequence, such as swapping A+ and B+, and then swapping A- and B-.
Two. Reasons for the electronic lock motor not returning to its original position.
1、The circuit board components are malfunctioning and cannot be reversed. This requires replacing the main board or repairing the switch behind the locking mechanism, which is causing the chip to fail to read the locking mechanism's entry and exit information.
2. If the hotel door lock cannot be turned at all, it may be due to a faulty motor wiring or a worn-out and damaged motor.
3、The guide plate spring broke, preventing the ejector pin from retracting after being pushed out, which created the illusion that the component could not be reversed.
4、Mechanical components: Inspect the empty spindle seat (allowing the lever to move freely). If the spindle is too long or excessively tight, it can cause the locking mechanism to become stuck in the empty spindle seat, preventing it from retracting.
