Safety Considerations

• Observe all 'Safety Considerations' for safe and proper operation to avoid hazards.
• ᜸ symbol indicates caution due to special circumstances in which hazards may occur.
᜸ Warning
Failure to follow instructions may result in serious injury or death.
01. Fail-safe device must be installed when using the unit with machinery that may
cause serious injury or substantial economic loss. (e.g. nuclear power control,
medical equipment, ships, vehicles, railways, aircraft, combustion apparatus,
safety equipment, crime / disaster prevention devices, etc.)
Failure to follow this instruction may result in personal injury, economic loss or fire.
02. Do not use the unit in the place where flammable / explosive / corrosive gas, high
humidity, direct sunlight, radiant heat, vibration, impact or salinity may be present.
Failure to follow this instruction may result in explosion or fire.
03. Do not use the brake for safety.
Failure to follow this instruction may result in personal injury or product and ambient
equipment damage.
04. Fix the unit on the metal plate.
Failure to follow this instruction may result in personal injury or product and ambient
equipment damage.
05. Do not connect, repair, or inspect the unit while connected to a power source.
Failure to follow this instruction may result in fire.
06. Install the unit after considering counter plan against power failure.
Failure to follow this instruction may result in personal injury, economic loss or fire.
07. Check 'Connections' before wiring.
Failure to follow this instruction may result in fire.
08. Do not disassemble or modify the unit.
Failure to follow this instruction may result in fire or electric shock.
09. Install the motor in the housing or ground it.
Failure to follow this instruction may result in personal injury, fire or electronic shock.
10. Make sure to install covers on motor rotating components.
Failure to follow this instruction may result in personal injury
11. Do not touch the unit during or after operation for a while.
Failure to follow this instruction may result in burn due to high temperature of the surface.
12. Upon occurrence of an error, disconnect the power source.
Failure to follow this instruction may result in personal injury, fire or electronic shock.
᜸ Caution
Failure to follow instructions may result in injury or product damage.
01. Use the unit within the rated specifications.
Failure to follow this instruction may result in fire or product damage.
02. Use a dry cloth to clean the unit, and do not use water or organic solvent.
Failure to follow this instruction may result in fire.
03. The motor may overheat depending on the environment.
Install the unit at the well-ventilated environment and forced cooling with a cooling fan.
Failure to follow this instruction may result in product damage or degradation by heat.
04. Keep the product away from metal chip, dust, and wire residue which flow into the unit.
Failure to follow this instruction may result in fire or product damage.

Cautions during Use

• Follow instructions in 'Cautions during Use' .
Otherwise, it may cause unexpected accidents.
• At low temperature, reducing the grease's consistency of ball-baring and etc. causes the
friction torque increment.
Start the motor gradually since motor's torque is in normal state.
• The clack sound may occur when power is ON or OFF on brake.
• Release the brake before motor drive by supplying power on brake.
The product life cycle is shorten and the static friction torque reduces due to worn out brake
pad.
• Be aware of backlash when positioning the motor in both CW/CCW directions.
Built-in gear type motor achieves low backlash due to high accuracy gear for positioning, but
the problem may occur when positioning the motor in both CW/CCW directions.
In this case, the control is required to determine the position in either direction.
