Omron 1S Series Instruction Manual page 10

 Do not touch the key grooves with bare hands if the Servomotor with shaft-end key grooves
is used.
Injury may result.
 Use non-magnetic mounting screws. Note also that the depth of any mounted screw does
not reach the effective thread length.
Equipment damage may result.
 Be sure to observe the allowable axial load for the Servomotor.
Equipment damage may result.
 Install equipment to prevent crash and reduce shock.
Do not run the Servomotor outside the operable range by the use of the drive prohibition
function such as overtravel.
Crash against the stroke edge may occur depending on stopping distance and equipment
damage may result.
 Do not block the intake or exhaust openings.
Do not allow foreign objects to enter the Servo Drive.
Fire may result.
 Tighten the mounting screws, terminal block screws, and shield clamp screws for the Servo
Drive and Servomotor to the specified torque.
Failure may result.
 Use crimp terminals to wire screw type terminal blocks.
Do not connect bare stranded wires directly to terminals blocks.
Fire may result.
 Always use the power supply voltage specified in this document.
Burning may result.
 Do not apply a commercial power supply directly to the Servomotor.
Fire or failure may result.
 Disconnect all connections to the Servo Drive and Servomotor before attempting a megger
test (insulation resistance measurement) on the Servo Drive and Servomotor.
Not doing so may result in Servo Drive and Servomotor failure.
Do not perform a dielectric strength test on the Servo Drive and Servomotor.
Internal elements may be damaged.
 Carefully perform the wiring and assembling.
Injury may result.
 Wear the protective equipment when installing or removing the main circuit connector, main
circuit connector A, main circuit connector B, control power supply connector, or motor con-
nector.
Do not apply a force after the protrusion of the connector opener reaches the bottom dead
center. (As a guide, do not apply a force of 100 N or more.)
 Be sure to install surge suppressors when you connect a load with an induction coil such as
a relay to the control output terminal. Malfunction or equipment damage may result.
 Be sure to install a shield clamp in accordance with a specified procedure. Electric shock
may result.
 Do not give impact on connectors such as tapping by hammer. Damage may result.
 Install an immediate stop device externally to the machine so that the operation can be
stopped and the power supply is cut off immediately.
Injury may result.
 Do not adjust or set parameters to extreme values, because it will make the operation unstable.
Injury may result.
 Secure a sufficient rigidity when you install a servo motor into equipment.
Equipment damage or malfunction may result.
 If a problem occurs in serial communications or the computer during a test operation, you
have no means to stop the Servomotor.
Connect an externally installed emergency stop switch, etc. to the Error Stop Input of the
general-purpose input so that the Servomotor can be stopped without fail.
