Status LED & Alarms


Alarms can be caused by any of the below reasons:

  • The enable signal of 5v to 24v is not received by the motor.
  • The motor received STEP signals that have acceleration or top RPM higher than the motor can support. This will also be affected by how much load is on the motor.
  • The power applied to the motor is less or more than the motor's specifications.
  • The current required to work under load is not enough.
  • The motor is not able to complete requestion rotation due to external mechanical issues such as the machine axis hitting something or getting stuck.
