12 Troubleshooting and Maintenance
12 - 30
G5-series Linear Motors/Servo Drives With Built-in EtherCAT Communications
The motor operates
momentarily, but then it does
not operate after that.
The position commands
given are too little.
Check the position data and
the electronic gear ratio at
the host controller.
Set the correct data.
The motor power cable is
wired incorrectly.
Check the wiring of the motor
power cable’s phases U, V,
and W.
Wire correctly.
The encoder cable is wired
incorrectly.
Check the external encoder
cable’s wiring.
Wire correctly.
The motor operates without a
command.
There are inputs of small
values in speed control
mode.
Check if there is an input in
speed control mode.
Set the speed command to
“0.” Alternatively, change the
mode to position control
mode.
The Servo Drive has broken
down.
–
Replace the Servo Drive.
The motor operates in the
reverse direction from the
command.
The value set in the
Movement Direction Setting
(3000 hex) is incorrect.
Check the set value of object
3000 hex.
Change the set value of
object 3000 hex.
The command given by the
host controller is incorrect.
•
The size of the absolute
command is set incorrect.
•
The polarity of an
incremental command is
set incorrect.
•
Check the actual and
target values.
•
Check the operation
direction.
The holding brake does not
work.
Power is supplied to the
holding brake.
Check to see if power is
supplied to the holding brake.
Check the brake interlock
output (BKIR) signal and the
relay circuit.
•
Check to see if the holding
brake is worn down.
Motor operation is unstable.
The motor power cable or
external encoder cable is
wired incorrectly.
Check the wiring of the motor
power cable’s phases U, V,
and W and check the
external encoder cable’s
wiring.
Wire correctly.
Low rigidity is causing
vibration.
Measure the vibration
frequency of the load.
Enable the damping control.
Set the damping filter
frequency.
The load mass exceeds the
Servo Drive’s allowable
value.
Calculate the load mass.
•
Check if manual tuning can
achieve proper adjustment.
•
Increase the motor
capacity.
Loose joint and/or large
clearance with the machine
Check the joint with the
machine.
Remove the joint looseness
with the machine.
The load and gain do not
match.
Check the response
waveforms for speed and
force.
Adjust the speed loop gain to
stabilize the operation.
