(*1)
Only
when
connected
Operation
release
Servo error Cause : It indicates 2 seconds has passed without making a
move since a move command was received.
1) Connection error or wire breakage on an
actuator cable
2) Brake is not released (when equipped with a
brake).
3) Load to the motor is high due to external force.
4) The resistance in the actuator sliding operation
is large.
Treatment : 1) Check the wiring condition of the actuator
cables.
2) If an improvement can be confirmed when 24V
DC, 150mA is supplied to BKRLS terminal in the
external brake input connector, a malfunction of
the controller can be considered. Please contact
IAI.
3) Confirm that there is no error in the mechanical
part assembly condition.
4) Move the slider or the rod to a point where it
would not hit the mechanical end and reboot the
system.
0C8 Overcurrent Cause : The output current in the power circuit section is
increased abnormally.
Treatment : This alarm will not be generated in normal
operation. Degradation in insulation of motor coil or
malfunction controller can be considered. Please
contact IAI.
0CA Overheat Cause : This indicates overheat (90 q C or more) of the
components inside the controller.
1) Operation is performed with the load condition
exceeding the specified range.
2) High temperature around the controller.
3) Load to the motor is high due to external force.
4) A faulty part inside the controller.
Treatment : 1) Revise the operation condition such as
decreasing the acceleration/deceleration speed.
2) Lower the ambient temperature of the controller.
3) Confirm that there is no error in the mechanical
part assembly condition.
(Note) This error would not normally occur. If it occurs,
confirm there is not (1) to (3) above. If the same
problem occurs again even with the process above,
malfunction of controller can be considered. Please
contact IAI.
0CB
Servo
motor
(*2)
Only
when
connected
Cold start
Current sensor offset
adjustment error
Cause : An error was found to the sensor in the status check
of the current detection sensor conducted at the
initializing process in the startup.
1) A breakdown of the current detection sensor or
peripheral component is supposed.
2) An error in the offset adjustment is supposed.
Treatment : A work (PC board) change or offset adjustment is
required.
Please contact IAI.
