A motor ground fault was detected. A connection or conductance error may have occurred in the motor
cable.
Turn the power OFF and ON once. Check connection and continuity of motor cable.
The main circuit bus voltage exceeded the tolerable value.
Check the primary power supply voltage. Turn the power OFF and ON once.
A power shutdown status of 50 msec or longer has occurred.
Check the power voltage. Turn the power OFF and ON once.
The input power (L1, L2, L3) has an open phase, the voltage is not within the specifications, or the 100V/
200V specifications changeover setting is incorrect.
Check the power connection, power state or the setting.
The main circuit bus voltage exceeded the tolerable value.
Check the power supply connection and power supply state.
A cooling fan stopped, and overheat occurred
Check the rotation of fan, and the connector connected to a fan
Overheating of the power module regenerative resistor was detected.
Turn the controller power OFF, wait a while, and then turn ON again. If it comes back, contact your service
provider.
The position detector's thermal protector activated.
Turn the controller power OFF, wait a while, and then turn ON again. Decrease the acceleration/
deceleration time of the operation speed, for instance.
Refer to "Detailed explanation of command words"/"Accel (Accelerate)," "Ovrd (Override)" and "Spd
(Speed)," or "Detailed explanation of Robot Status Variable"/"M_SetAdl," "M_LdfAct" and "Functions set
with parameters"/"JADL (Optimum acceleration/deceleration adjustment rate)" of the Separate Volume,
"INSTRUCTION MANUAL/Detailed Explanation of Functions and Operations."
It moved 45 mm/sec or faster with the absolute position linear scale during initialization.
Turn the power OFF and ON once. If it comes back, contact your service provider.
A speed exceeding the motor's tolerable speed was detected.
Turn the power OFF and ON once. If it comes back, contact your service provider.
A servo amplifier or power supply overcurrent was detected. An error was detected in the servo amplifier's
gate circuit. A connection or conductance error may have occurred in the motor cable.
Confirms the connection of the machine cable and the locomotion-axis cable. If it comes back, contact
your service provider.
