*1. This warning is not displayed on MR-J3-70B/100B servo amplifiers with cooling fans.
Content
STO warning (Only the MR-J3- BS)
STO I/O signal turns off.
Open battery cable warning
The absolute position detection system battery
voltage is low.
Home position setting warning
The zero return could not be set to the accurate
position.
Battery warning
The voltage of the battery for the absolute position
detection system is low.
Excessive regenerative warning
There is a possibility that regenerative power may
exceed the permissible regenerative power of the
built-in regenerative brake resistor or the
regenerative brake option.
Overload warning
There is a possibility that overload (error code:
2050) or overload (error code: 2051) may occur.
Absolute position counter warning
Absolute position encoder pulses are faulty.
Parameter warning
Parameters are outside the setting range.
Servo forced stop warning
Servo amplifier input signal EM1 is OFF.
A watchdog error occurred on the 20SSC-H.
Cooling fan speed reduction warning
The rotation speed of the servo amplifier's cooling
*1
fan fell below the warning level.
Main circuit OFF warning
The servo ON signal turned ON with the main
circuit power OFF.
Overload warning 2
Operation in which a current exceeding the rating
flow intensity in any of the U, V or W phases of the
servo motor, is repeated.
Output watt excess warning
The status in which the output wattage (speed ×
torque) of the servo motor exceeds the rated
output.
13.2 Check Error Code
Action
• Properly connect the STO I/O signal connector.
• Change the STO cable.
• Change MR-J3-D05.
• Change the external device, or review the setting.
Replace the servo amplifier battery.
• Remove the cause of drop pulses.
• Reduce the creep speed.
Replace the servo amplifier battery.
• Reduce the frequency of positioning.
• Change the regenerative brake option to the one with a
larger capacity.
• Reduce the load.
Refer to the manual of the servo amplifier.
• To reduce the noise, follow the servo amplifier manual.
• Replace the servo motor.
Set the servo parameters correctly.
Ensure safety and deactivate the forced stop.
If this error occurs after rebooting and initializing the
20SSC-H, the module needs repair.
Consult your local Mitsubishi Electric representative.
• Replace the cooling fan of the servo amplifier.
• Replace the servo amplifier.
Turn the main circuit power ON.
• Reduce the positioning frequency at the specific
positioning address.
• Reduce the load.
• Exchange the servo amplifier/servo motor with one of a
larger capacity.
• Reduce the rotation speed of the servo motor.
• Reduce the load.
