Servomotor and stepping motor driver units may stop the motor to protect against overload, overvoltage, and overheating. At that time, an alarm signal is sent from the driver unit to the board (application).
When the alarm signal is received, the operation of the axis set for synchronization is also stopped.
When an application receives an alarm signal, it should disconnect the system, take action, and clear the alarm signal. At this time, an alarm clear signal is sent.
