(6) Usage methods
CAUTION
Immediately turn OFF the power if smoke, abnormal sounds or odors are emitted from the
control unit, servo amplifier or servomotor.
Always execute a test operation before starting actual operations after the program or
parameters have been changed or after maintenance and inspection.
The units must be disassembled and repaired by a qualified technician.
Do not make any modifications to the unit.
Keep the effect or magnetic obstacles to a minimum by installing a noise filter or by using
wire shields, etc. Magnetic obstacles may affect the electronic devices used near the control
unit or servo amplifier.
When using the CE Mark-compliant equipment, refer to the "EMC Installation Guidelines"
(data number IB(NA)-67339) for the motion controllers and refer to the corresponding EMC
guideline information for the servo amplifiers, inverters and other equipment.
Use the units with the following conditions.

(7) Remedies for errors
CAUTION
If an error occurs in the self diagnosis of the control unit or servo amplifier, confirm the
check details according to the instruction manual, and restore the operation.
If a dangerous state is predicted in case of a power failure or product failure, use a
servomotor with magnetic brakes or install a brake mechanism externally.
Use a double circuit construction so that the
magnetic brake operation circuit can be
operated by emergency stop signals set
externally.
If an error occurs, remove the cause, secure
the safety and then resume operation.
The unit may suddenly resume operation
after a power failure is restored, so do not go
near the machine. (Design the machine so
that personal safety can be ensured even if
the machine restarts suddenly.)
Shut off with servo ON signal OFF,
alarm, magnetic brake signal.
