Name Description
When Error Checked Error Processing Corrective Action
•
The rated current of the servo
motor is exceeded.
•
Reduce the load.
•
Load inertia or friction is too large.
A
Overload
•
Hunting due to parameter setting
mistake.
•
Reconsider the servo parameters.
2050
M
Overload 1
•
An overload current of about 200%
has been continuously supplied to
the servo amplifier and servomotor.
•
Check if there has been a collision at
the machine.
•
If the load inertia is very large, either
increase the time constant for
acceleration and deceleration or
reduce the load.
•
If hunting occurs, adjust the position
loop gain in the servo parameters.
•
Check the connection of U, V, W of the
servo amplifier and servomotor.
•
Check for disconnection of the encoder
cable.
•
Replace the servomotor.
2051
M
Overload 2
•
The servo amplifier and servomotor
were overloaded at a torque close
to the maximum torque (95% or
more of the current control value).
At any time during operation Immediate stop
•
Check if there has been a collision at
the machine.
•
If the load inertia is very large, either
increase the time constant for
acceleration and deceleration or
reduce the load.
•
If hunting occurs, adjust the position
loop gain / position control gain 1, 2,
speed loop gain/ speed control gain 1,
2 in the servo parameters.
•
Check the connection of U, V, W of the
servo amplifier and servomotor.
•
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.
