12 Troubleshooting and Maintenance

G5-series Linear Motors/Servo Drives With Built-in EtherCAT Communications
16 hex
0 hex Overload
*3
When the feedback value for force
command exceeds the overload level
specified in the Overload Detection Level
Setting (3512 hex), overload protection is
performed according to the overload
characteristic curve set in the Motor
Overload Curve Selection (3929 hex).
Check if force (current) waveforms
oscillate or excessively fluctuate vertically
during analog output or communications.
Check the overload warning display and
the load rate through communications.
•
The load was heavy, the effective force
exceeded the rated force, and
operation continued too long.
•
Increase the capacities of the Servo
Drive and the motor. Set longer
acceleration and deceleration times.
Reduce the load.
•
Vibration or hunting occurred due to
faulty gain adjustment. The motor
vibrates or makes unusual noise. The
Mass Ratio (3004 hex) setting is faulty.
•
Readjust the gain.
•
The motor wiring is incorrect or broken.
•
Connect the motor cable as shown in
the wiring diagram. Replace the cable.
•
The machine was hit by an object, or
the machine load suddenly became
heavy. The machine was distorted.
•
Remove the distortion from the machine.
Reduce the load.
•
The brake remains ON.
•
Measure the voltage at the brake
terminals. Turn OFF the brake.
•
When multiple machines were wired,
the wiring was incorrect and the motor
cable to was connected to a motor for
another axis.
•
Wire the motor and the external encoder
correctly so that the wires match the
axes.
18 hex
0 hex Regeneration
Overload
*4
The regenerative energy exceeds the
processing capacity of the Regeneration
Resistor.
Check the load rate of the Regeneration
Resistor through communications. This
Regeneration Resistor cannot be used for
continuous regenerative braking.
•
The regenerative energy during
deceleration caused by a large load
mass increased the converter voltage,
and then insufficient energy absorption
by the Regeneration Resistor further
increased the voltage.
•
Check the operation pattern (speed
monitor). Check the load rate of the
Regeneration Resistor and check for the
excessive regeneration warning display.
Increase the capacities of the Servo
Drive and the motor, and length the
deceleration time. Use an External
Regeneration Resistor.
•
The motor speed is too high to absorb
the regenerative energy within the
specified deceleration time.
•
Check the operation pattern (speed
monitor). Check the load rate of the
Regeneration Resistor and check for the
excessive regeneration warning display.
Increase the capacities of the Servo
Drive and the motor, and length the
deceleration time. Reduce the motor
speed. Use an External Regeneration
Resistor.
•
The operating limit of the external
resistor is limited to a 10% duty.
•
Set the Regeneration Resistor Selection
(3016 hex) to “2.”
1 hex Regeneration
Tr Error
The Servo Drive regeneration drive Tr is
faulty.
Replace the Servo Drive.
Error No.
