(7) Usage methods
(8) Corrective actions for errors
CAUTION
 Immediately turn OFF the power if smoke, abnormal sounds or odors are emitted from the
Motion controller, servo amplifier or servo motor.
 Always execute a test operation before starting actual operations after the program or
parameters have been changed or after maintenance and inspection.
 Do not attempt to disassemble and repair the units excluding a qualified technician whom
our company recognized.
 Do not make any modifications to the unit.
 Keep the effect or electromagnetic obstacles to a minimum by installing a noise filter or by
using wire shields, etc. Electromagnetic obstacles may affect the electronic devices used
near the Motion controller or servo amplifier.
 When using the CE Mark-compliant equipment, refer to this manual for the Motion
controllers and refer to the corresponding EMC guideline information for the servo
amplifiers, inverters and other equipment.
 Use the Motion controller with the conditions described in this manual (Page 15
Motion Controller (Q170MSCPU) Specifications).
CAUTION
 If an error occurs in the self diagnosis of the Motion controller 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 servo
motor with electromagnetic brakes or install a brake mechanism externally.
 Use a double circuit construction so that the electromagnetic 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 after
alarm release.
 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.)
