(3) Trial operation and adjustment
CAUTION
Check and adjust each 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
CAUTION
Install an external emergency stop circuit so that the operation can be stopped and power
shut OFF immediately.
Unqualified persons must not disassemble or repair the unit.
If the alarm is reset (RST) with the operation start signal (ST) ON, the servomotor will restart
suddenly. Confirm that the operation signal is OFF before resetting. Failure to observe this
could lead to accidents.
Never make modifications.
Reduce magnetic interference by installing a noise filter. The electronic devices used near the
servo amplifier could be affected by magnetic noise.
Always use the linear servomotor and servo amplifier with the designated combination.
The linear servomotor basically does not have any devices such as the magnetic brakes
installed. Thus, when using this for an axis onto which an unbalance force is applied, such as
a gravity axis, install a stopping device on the machine side to secure safety.
Always carry out trial operation after changing the program or parameters, and after
maintenance and inspection.
Do not enter the machine's movable range during automatic operation.
For an unbalanced axis, such as a gravity axis, basically balance it with a device such as a
counterbalance. With the linear motor, the continuous thrust is lower than the rotary motor, so
if the axis is unbalanced the motor's heating amount will increase. If an error should occur,
the axis will drop naturally. This is hazardous as the dropping distance and dropping speed
are large.
(5) Troubleshooting
CAUTION
If a hazardous situation is predicted during stop or product trouble, install an external brake
mechanism.
If an alarm occurs, remove the cause and secure the safety before resetting the alarm.
Never go near the machine after restoring the power after a failure, as the machine could start
suddenly. (Design the machine so that personal safety can be ensured even if the machine
starts
suddenly.)
