5.2.1. Servo Motor Alarm Code
When an error occurs, the 7 segment LEDs of the motor drive will flicker. As well, the
corresponding alarm code is generated. It is of “Err **” form and the “**” will express the
corresponding alarm code.
In this case, take measures against the corresponding alarm code referring to the
following table.
