  • Hello I recently read your site and have a question. I have a driver model DM2722A but I can't connect it to my usb controller due to the fact that the driver is not marked enable, but instead it is marked: mf-, mf +, alm-, alm +. I will be very grateful if you explain to me the meaning of the latter and tell me what should be related to "enable" Thanks in advance!

    Not a problem. The ALM is rather self-explanatory as this is a closed-loop stepper motor and driver that you are using. The ALM (alarm) is a signal that is used to tell the driver/controller that the motor is not in the same condition that the driver expects. In a closed-loop system, the motor has an encoder that tells the driver exactly how many steps that it turned, and if this value does not coincide with the driver's outputted number of steps, and within a specified amount of time, the alarm will trigger so the system can stop and the workpiece can be salvaged. The MF is simply a signal that tells the driver that there is impending direction and step pulses coming. If the MF signal is high, then that is similar to an enable signal.
