2052
Excessive error
•
The droop pulses of the deviation
counter exceeded the error excessive
alarm level set in the servo parameters.
Immediate stop
•
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.
2086
RS232
communication
error
•
Parameter unit communication error
•
Check for disconnection of the parameter unit
cable.
•
Replace the parameter unit.
2102
Battery warning
•
The voltage of the battery installed in
the servo amplifier has become low.
•
Replace the battery.
(MR-JBAT- )
2103
Battery
disconnection
warning
•
The power supply voltage to the
absolute position sensor has become
low.
•
Replace the battery.
•
Check for disconnection of the encoder cable.
•
Replace the servomotor.
•
Replace the servo amplifier.
2140
Excessive
regeneration
warning
•
An excessive regeneration error (2030)
is likely to occur (regeneration of 85%
of the maximum load capacity for the
regenerative resistor has been
detected).
•
Refer to the details on the excessive
regeneration error (2030).
2141
Overload
warning
•
An overload error (2050, 2051) is likely
to occur (85% of overload level
detected).
•
Refer to the details on the overload errors
(2050, 2051).
2146
Servo
emergency stop
•
The connection between 1A and 1B
(emergency stop input) of CN6 of the
servo amplifier encoder has been
broken.
Operation
continues
•
Establish a short circuit between 1A and 1B of
CN6 of the servo amplifier encoder.
2147
Emergency stop
•
An emergency stop (EMG) signal has
been input from the servo system CPU.
Immediate stop
•
Release the emergency stop.
2149
Main circuit OFF
warning
•
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.
•
Turn the main circuit contactor or circuit power
supply ON.
2196
Home position
setting error
warning
•
After a home position set command, the
droop pulses did not come within the in-
position range.
At any time during operation
Operation
continues
•
Re-attempt zeroing.
