For Safe Use
1. Special precautions for linear servo system
DANGER
The linear servo system uses a powerful magnet on the secondary side. Thus, caution must
be taken not only by the person installing the linear motor, but also the machine operators.
For example, persons wearing a pacemaker, etc., must not approach the machine.
The person installing the linear motor and the machine operator must not have any items
(watch or calculator, etc.) which could malfunction or break due to the magnetic force on their
body.
Always use nonmagnetic tools for installing the linear motor or during work in the vicinity of
the linear motor.
(Example of nonmagnetic tool)
Explosion-proof beryllium copper alloy safety tool: Nihon Gaishi
2. Electric shock prevention
DANGER
Do not open the front cover while the power is ON or during operation. Failure to observe this
could lead to electric shocks.
Do not operate the machine with the front cover removed. The high voltage terminals and
charged sections will be exposed, and may pose a risk of electric shocks.
Do not remove the surface cover even when the power is OFF unless carrying out wiring
work or periodic inspections. The inside of the servo amplifier is charged, and may pose a
risk of electric shocks.
Wait at least 10 minutes after turning the power OFF, before starting wiring or inspections.
Failure to observe this could lead to electric shocks.
Ground the servo amplifier and linear servomotor with Class 3 grounding or higher.
Wiring and inspection work must be done by a qualified technician.
Wire the servo amplifier and linear servomotor after installation. Failure to observe this could
lead to electric shocks.
Do not touch the switches with wet hands. Failure to observe this could lead to electric shocks.
Do not damage, apply forcible stress, place heavy items or engage the cable. Failure to observe
this could lead to electric shocks.
