Type
Name Description
When Error Checked Error Processing Corrective Action
•
The deviation counter value
exceeded the specified value.
•
Inertia is too large to make enough
acceleration.
•
Reconsider the servo parameters.
A
•
Encoder or cable fault.
•
Change the encoder or cable.
2052
M
Excessive error
•
The droop pulses of the deviation
counter exceeded the error
excessive alarm level set in the
servo parameters.
•
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 the encoder cable for wire
breakage.
•
Replace the servomotor.
•
If the voltage of the bus in the servo
amplifier has dropped (charge lamp has
gone out), replace the servo amplifier.
2057

Replace the servomotor.
•
Replace the servo amplifier.
2140
M
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).
A

The 80% level of the overload error
(2050) level was detected.
•
Refer to details of the overload error
(2050).
2141
M
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).
2143
A
Absolute value
counter warning
•
Encoder fault.
•
Change the encoder.
2146
M
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.
A
•
Brought to an emergency stop.
2147
M
Emergency stop
•
An emergency stop (EMG) signal
has been input from the servo
system CPU.
Immediate stop
•
Release the emergency stop.
2149
M
Main circuit OFF
warning
•
The servo ON (SON) signal was
turned ON while the contactor was
OFF.
•

215 V or lower at 50 rpm or lower.
•
Turn the main circuit contactor or circuit
power supply ON.
2196
M

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.
