2.5 Replacing Motor
The motor is to be replaced by our service engineer. If it is replaced by the customer,
we will not guarantee any consequential trouble or accident.
• The motor should be replaced with a new one only after the controller power is
turned off with the power supply plug removed. If the work is done while the
power is turned on, you may get an electric shock or the robot may malfunction,
which is very dangerous.
• When replacing the motor, take careful precautions not to exert a heavy impact
on the motor shaft. Otherwise, the motor and encoder may be damaged.
• NEVER disassemble the motor and encoder. Otherwise, they cannot be used
due to positional shift, etc.
•
Once the motor has been changed, the mechanical home point origin (or origin)
will shift and precise control will not be possible. To avoid this, home return
operation is necessary after motor replacement.
For the home return procedures, see Section 4.
