(3) Trial operation and adjustment
Check and adjust each program and parameter before starting operation. Failure to do so could
lead to unforeseen operation of the machine.
Do not make remarkable adjustments and changes as the operation could become unstable.
(4) Usage methods
Install an external emergency stop circuit so that the operation can be stopped and power
shut off immediately.
Turn the power OFF immediately if smoke, abnormal noise or odors are generated from the
servo drive unit or servomotor.
Unqualified persons must not disassemble or repair the unit.
Never make modifications.
Reduce magnetic damage by installing a noise filter. The electronic devices used near the
servo drive unit could be affected by magnetic noise.
Use the servo drive unit, servomotor and regenerative resistor with the designated combination.
Failure to do so could lead to fires or trouble.
The brake (magnetic brake) assembled into the servomotor is for holding, and must not be used
for normal braking.
There may be cases when holding is not possible due to the magnetic brake's life or the
machine construction (when ball screw and servomotor are coupled via a timing belt, etc.).
Install a stop device to ensure safety on the machine side.
After changing the programs/parameters or after maintenance and inspection, always test the
operation before starting actual operation.
Do not enter the movable range of the machine during automatic operation. Never place body
parts near or touch the spindle during rotation.
Follow the power supply specification conditions given in the separate specifications manual for
the power (input voltage, input frequency, tolerable sudden power failure time, etc.).
Set all bits to "0" if they are indicated as not used or empty in the explanation on the bits.
Do not use the dynamic brakes except during the emergency stop. Continued use of the
dynamic brakes could result in brake damage.
If a breaker is shared by several power supply units, the breaker may not activate when a
short-circuit fault occurs in a small capacity unit. This is dangerous, so never share the
breakers.
