Electromagnetic brake board for STEP400
Some stepper motors are made with an electromagnetic brake built-in. Typically, stepper motors have a holding torque which holds loads even when stopped; however, when power is lost, the holding force is lost and the suspended load will fall.
An electromagnetic brake is a device that locks the shaft of a motor and only releases when the shaft is energized. In the event of a power failure to the motor, the brake will immediately lock the shaft which prevents the load from moving or falling. Vertically moving loads should especially consider using one of these devices.
When using a stepper motor with an electromagnetic brake, it is necessary to release/lock the brake depending on the status of the motor. This brake add-on board is designed to be controlled in conjunction with the STEP400 motor controller.
