3. To prevent injury, note the following
Only the voltage specified in the Instruction Manual should be applied to each terminal, Otherwise, a burst,
damage, etc. may occur.
Connect the terminals correctly to prevent a burst, damage, etc.
Ensure that polarity ( ,
Take safety measures, e.g. provide covers, to prevent accidental contact of hands and parts (cables, etc.)
with the servo amplifier heat sink, regenerative resistor, servo motor, etc. since they may be hot while
power is on or for some time after power-off. Their temperatures may be high and you may get burnt or a
parts may damaged.
During operation, never touch the rotating parts of the servo motor. Doing so can cause injury.
4. Additional instructions
The following instructions should also be fully noted. Incorrect handling may cause a fault, injury, electric shock,
etc.
(1) Transportation and installation
Transport the products correctly according to their mass.
Stacking in excess of the specified number of products is not allowed.
Do not carry the servo motor by the cables, shaft or encoder.
Install the servo amplifier in a load-bearing place in accordance with the Instruction Manual.
Do not climb or stand on servo equipment. Do not put heavy objects on equipment.
The servo amplifier and servo motor must be installed in the specified direction.
Leave specified clearances between the servo amplifier and control enclosure walls or other equipment.
Do not install or operate the servo amplifier and servo motor which has been damaged or has any parts
missing.
Do not block the intake and exhaust areas of the servo amplifier. Doing so may cause faults.
Do not drop or strike servo amplifier or servo motor. Isolate from all impact loads.
Securely attach the servo motor to the machine. If attach insecurely, the servo motor may come off during
operation.
The geared servo motor must be installed in the specified direction to prevent oil leakage.
Take safety measures, e.g. provide covers, to prevent accidental access to the rotating parts of the servo
motor during operation.
Never hit the servo motor or shaft, especially when coupling the servo motor to the machine. The encoder
may become faulty.
Do not subject the servo motor shaft to more than the permissible load. Otherwise, the shaft may break.
When the equipment has been stored for an extended period of time, contact your local sales office.
When treating the servo amplifier be careful about the edged parts such as the corners of the servo
amplifier.
The servo amplifier must be installed in the metal cabinet.
