Error Cause
Description
• The droop pulses of the deviation
counter exceeded the error excessive
alarm level set in the servo parameters.
• Parameter unit communication error
• The voltage of the battery installed in
the servo amplifier has become low.
• The power supply voltage to the
absolute position sensor has become
low.
• An excessive regeneration error (2030)
is likely to occur (regeneration of 85%
of the maximum load capacity for the
regenerative resistor has been
detected).
• An overload error (2050, 2051) is likely
to occur (85% of overload level
detected).
• The connection between 1A and 1B
(emergency stop input) of CN6 of the
servo amplifier encoder has been
broken.
• An emergency stop (EMG) signal has
been input from the servo system CPU.
• The servo ON (SON) signal was turned
ON while the contactor was OFF.
• The main circuit bus voltage fell to 215
V or lower at 50 rpm or lower.
• After a home position set command, the
droop pulses did not come within the in-
position range.

Corrective Action
• Check if there has been a collision at the
machine.
• Increase the time constant for acceleration and
deceleration.
• Increase the position loop gain / position control
gain 1, 2, in the servo parameters.
• Check for disconnection of the encoder cable.
• Replace the servomotor.
• If the voltage of the bus in the servo amplifier
has dropped (charge lamp has gone out),
replace the servo amplifier.
• Check for disconnection of the parameter unit
cable.
• Replace the parameter unit.
• Replace the battery.
(MR-JBAT- )
• Replace the battery.
• Check for disconnection of the encoder cable.
• Replace the servomotor.
• Replace the servo amplifier.
• Refer to the details on the excessive
regeneration error (2030).
• Refer to the details on the overload errors
(2050, 2051).
• Establish a short circuit between 1A and 1B of
CN6 of the servo amplifier encoder.
• Release the emergency stop.
• Turn the main circuit contactor or circuit power
supply ON.
• Re-attempt zeroing.
