SunStar Fortuna 5 Series - Breakdown and Troubleshooting; Error Indicators and Troubleshooting Steps

BREAKDOWN AND TROUBLESHOOTING
^ If the machine breaks down while using the servo motor due to an unforseen change in the machine, the error indicators mentioned
below will appear In the displayer of the program unit or simple program unit according to the self-checking function of the machine.
The machine will then stop along with the sound of a waming buzzer. When an error Indicator appears, follow the solution steps
described below and resume work. If the problem is not solved after taking these measures, contact a company branch office.

This error sign is seen when the user connects
the location sensor while the power is still on
»Turn the power off and on
again before using it
61 Er
This error sign is seen when the user Uie user
removes the location sensor while the power is still on
• Turn the power off and on
again before using it
126 Er ■
This error sign is seen when the motor's rotor magnet
and stator coil's electric current flow does not match
• Check the condition of the motor's
127 Er
This error sign appears when the direction of encoders
R S T and the direction of A B do not match.
• Check the encoder cable and
the connector
128 Er When there is no signal from encoders R S T
• Check the encoder cable and
the connector
129 Er When the motor is overloaded
