About Stepper Driver ALM and BRK Ports
If you simply control the operation of the stepper motor, then ALM and BRK do not need to be connected. They are only used to output signals and are not used to control the motor. Here are some descriptions of these two ports:
Stepper drivers are very important for the normal operation of stepper motors and brushless DC motors, so in order to make the motor work better, we need to understand the stepper driver. Today, let us first take a look at the signal output ports ALM and BRK of the driver.
If you simply control the operation of the stepper motor, then ALM and BRK do not need to be connected. They are only used to output signals and are not used to control the motor. Here are some descriptions of these two ports:
1.ALM
ALM is the alarm signal output port. When used, it needs to be connected to the signal receiving end of the driver.
When the driver triggers an alarm, the internal switch between ALM+ and ALM- is closed and an alarm signal is output to the controller.
BRK is the brake signal output port. When using it, you need to connect the relay and the brake of the motor.
When the driver outputs the braking signal, the relay is disconnected, the motor is braked and stops running.
When using the drive's BRK port to control the brake for braking, the reaction speed is faster than when the motor's brake is powered alone.
