CAUTION
(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 of parameter as the operation could
become unstable.
The usable motor and unit combination is predetermined. Always check the models before
starting trial operation.
If the axis is unbalanced due to gravity, etc., balance the axis using a counterbalance, etc.
The linear servomotor does not have a stopping device such as magnetic brakes. Install a
stopping device on the machine side.
(4) Usage methods
In abnormal state, 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 unit
or motor.
Do not disassemble or repair this product.
Never make modifications.
When an alarm occurs, the machine will start suddenly if an alarm reset (RST) is carried out
while an operation start signal (ST) is being input. Always confirm that the operation signal is
OFF before carrying out an alarm reset. Failure to do so could lead to accidents or injuries.
Reduce magnetic damage by installing a noise filter. The electronic devices used near the
unit could be affected by magnetic noise. Install a line noise filter, etc., if there is a risk of
magnetic noise.
Use the unit, motor and regenerative resistor with the designated combination. Failure to do so
could lead to fires or trouble.
The brake (magnetic brake) of the servomotor are 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, the machine
construction (when ball screw and servomotor are coupled via a timing belt, etc.) or the
magnetic brake’s failure. 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 each specification 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 circuit protector for the main circuit power supply is shared by several units, the circuit
protector may not activate when a short-circuit fault occurs in a small capacity unit. This is
dangerous, so never share the circuit protector.
