Principle Overview
This driver uses advanced motor circuit current precise detection technology, brushed DC motor speed self detection technology, regenerative current constant current braking (or braking) technology, and powerful PID regulation technology to perfectly control motor starting, braking (braking), commutation control, and stall protection. The motor response time is short and the recoil force is small, and the output current is real-time regulated to prevent overcurrent, effectively protecting the motor and driver.
| Motor start-up control:The soft start method with automatic current regulation allows the motor to start quickly without strong recoil vibration. Support acceleration and deceleration time configuration. |
| Motor brake control:The energy consumption braking method with automatic current regulation has a short motor braking time without strong impact vibration. Support brake time configuration. |
| Motor commutation control:The process of switching between forward and reverse rotation of the motor is controlled internally by the driver, which automatically performs soft braking and soft start control. No matter how frequently the commutation signal changes, it will not cause damage to the driver or motor. |
| Motor torque control:Control the motor torque by adjusting the output current. |
| Motor self testing speed and stable speed control:By measuring the frequency of motor current fluctuations, the speed of the motor is indirectly measured, and PID regulation is used to achieve stable speed. |
| Motor overload and locked rotor protection:When the motor is overloaded, the driver will limit the current output, effectively protecting the motor; When the motor is stuck, the driver can detect this state and brake the motor. |
| Internal interference suppression:The coupling between the drive circuit and the control circuit through interference consumption and transient interference suppression can effectively ensure that the control circuit is not affected by the interference of the drive circuit. |
| External interference suppression:Use ESD protection devices and electrostatic discharge circuits to provide ESD protection for all interfaces, ensuring stable operation of internal circuits and protecting internal devices from transient high voltage static electricity applied to the interfaces. |

Typical Connection Example
1. The connection method of preset forward and reverse speed jog control
The working process of using potentiometer speed regulation in jog control mode is as follows: press B1, the motor rotates forward; B1 pops up, the motor stops; When the motor stops after the forward limit is reached, pressing B1 again is ineffective; Press B2 to reverse the motor; B2 pops up, the motor stops; When reversing the limit, the motor stops, and pressing B2 again is ineffective.
If there is significant environmental interference, a 104 capacitor can be connected in parallel between AI1 and COM, as well as between AI2 and COM. If using a battery to power the driver, it is recommended to connect a 10A fuse in series with the power interface.
2. Single potentiometer PWM speed control method connection
This connection can be used to adjust the speed of the motor in both forward and reverse directions using a potentiometer. The motor can be enabled and the direction of rotation can be switched by a switch, and the forward and reverse directions can be limited by a limit switch.
3. Connection method for preset speed self-protection control
The working process of this self-protection contact control method is: press B1 once, the motor rotates forward until the forward limit switch triggers the motor to stop, or press B2 to reverse the motor; Press B2 to reverse the motor until the reverse limit switch triggers the motor to stop, or press B1 to make the motor rotate forward.
If there is significant environmental interference, a 104 capacitor can be connected in parallel between AI1 and COM, as well as between AI2 and COM. If using a battery to power the driver, it is recommended to connect a 10A fuse in series with the power interface.
4. Connection method for 485 communication multi machine control
The 485 communication lines of each drive are connected in parallel in the A-A and B-B directions, followed by a 485 master station. The 485 master station independently operates each drive based on the slave station address configured by the drive. The address configured for each drive should be unique and cannot be duplicated with other drives.
Dimension definition
The size is 5.5cm × 5.5cm × 3cm. The installation hole diameter is 3mm, and it is recommended to use M3 screws for fixing. Be careful not to short-circuit the back circuit during installation.
