Special functions

1.One-click motor phase sequence adaptation

The three-phase lines and three Hall signal lines of the motor do not need to be connected to the driver in sequence. Just one click operation is required to learn the Hall sequence of the motor.

After performing six commutation controls on the motor, the learning is completed and the motor can be driven normally.

2. Automatic acceleration and deceleration control for reciprocating motion

When controlling reciprocating motion, the driver can pre-learn the total stroke of the reciprocating motion (or directly configure the value), and automatically control the motor to move rapidly and smoothly to the target position in accordance with Newton's laws of motion based on the configured acceleration and deceleration acceleration and maximum speed.

3. The motor can be adjusted at any position within a fixed stroke

The driver can pre-learn the total stroke of the reciprocating motion (or directly configure the value), and then use a potentiometer, analog quantity or PWM to adjust the position of the motor within a fixed stroke. The motor position is linearly related to the input quantity. If the potentiometer is rotated to the midpoint and the input duty cycle is given at 50%, then the motor will move to the midpoint of the stroke.

4. Brushless motors can also be steplessly controlled

Select the input signal as PWM/ frequency/pulse, configure the pulse type as pulse, and set the working mode as position control. Then, the brushless motor can be operated like a stepper motor. One pulse signal can control the motor's rotation Angle, and another pulse signal can control the rotation direction. The rotation Angle of the motor corresponding to each pulse can be configured.

5.Brushless motors can also be servo-controlled

Under the 485 communication control mode, the target position (absolute position or relative to the current position) can be directly given to rotate the driver to the target position. The driver will automatically control the motor to move rapidly and smoothly to the target position in accordance with Newton's laws of motion based on the set acceleration and deceleration acceleration and maximum speed. During the movement process, the driver can predict the remaining time required to complete the task.

The size definition of AQMD2408BLS-M: The size of the driver is 5.5mm x 5.5mm x 1.7mm, the diameter of the installation hole is 3mm, and the distance from the center of the installation hole to the side is 3.4mm.

4. Connection method of pulse signal position control for single-chip microcomputer

The working process of this connection method is as follows: The power supply of the single-chip microcomputer is grounded to the COM port of the drive module. IN1 is connected to IO1 of the single-chip microcomputer to determine the number of pulses, which is used for motor position control. VO is connected to IO0 of the single-chip microcomputer and is used to complete signal control. IN2 and IN3 are connected to the two IOs of the single-chip microcomputer to control the forward and reverse rotation of the motor and emergency braking.

5. Connection method for 485 multi-site control

The 485 communication lines of each driver are connected in parallel in the form of A-A and B-B and then linked to A 485 master station. The 485 master station operates each driver independently through the slave station address configured by the driver. The address configured for each drive should be different and cannot be duplicated with other drives.

6. Connection method of CAN multi-node control

The CAN communication lines of each driver are connected in parallel in the form of CANH-CANH and CANL-CANL and then connected to the CAN client. At least one 120Ω resistor is connected in parallel on the CAN bus. The CAN client operates each driver independently through the node ID configured on the driver. The node ID configured for each drive should be different and cannot be duplicated with that of other drives.
