SAFETY PRECAUTIONS
(35)
Do not fall or topple over the equipment when carrying or installing.
(36)
Do not climb the motor or do not place a heavy item on the motor.
(37)
Do not block radiation slits of the driver and do not put a foreign matter into the driver.
(38)
Do not use the equipment under direct sunlight. When storing the equipment, avoid direct sunlight and
store under conditions of operating temperatures and humidity.
(39)
Be sure not to disassemble or modify the equipment. Disassembling and repair is allowed only for the
manufacturer or sales agency authorized by the manufacturer.
(40)
Do not start / stop the motor by the servo signal (SRV-ON). Built-in dynamic brake circuit may be
damaged.
(41)
Use a motor and a driver in combination specified by the manufacturer. A customer shall be
responsible for verifying performances and safety of combination with other driver.
(42)
A failure of a motor or a combined driver may cause burning of motor, or emission of smoke and
dust. Take this into consideration when the application of the machine is clean room related.
(43)
Install the equipment adequately in consideration of output and main unit weight.
(44)
Keep the ambient conditions of an installed motor within a range of allowable ambient temperatures
and of allowable humidity.
(45)
Install the equipment by specified procedures and in specified orientation.
(46)
Install the devices by keeping specified distances between a driver and inside control panel or other
devices.
(47)
If a motor has an eyebolt, use the eyebolt to carry the motor only. Do not use the eyebolt to carry
equipment.
(48)
Connect a relay breaking upon emergency stop in series with a brake control relay.
(49)
For a test run, hold down a motor and disconnect from a mechanical system to verify operations before
installing on the equipment.
(A motor must run smoothly at 30 r/min driven with an driver. )
(50)
Verify that an input power supply voltage satisfies the driver specifications before turning on the
power and start operation.
An input voltage higher than rated may cause ignition and smoking in the driver, which may cause
runaway or burning of a motor in some cases.
(51)
When an alarm status occurs, remove a cause of the problem before restarting.
Careless restarting without removing a cause of problem may cause malfunction or burning of a motor.
(52)
The built-in brake of the motor may not be able to hold due to expiring useful life or a mechanical
structure.Install a braking device on the equipment to secure safety.
(53)
Pay attention to heat radiation. The driver generates heat by operating a motor. A driver used in a
sealed control box may cause an extreme rise of temperature.
Consider cooling so that an ambient temperature around the driver satisfies an operating range.
(54)
Maintenance and inspection is allowed only for a specializing person.
(55)
Turn off the power when the equipment is not used for a long term.
(56)
The cooling fan in the top side of size H stops for energy saving when driver is servo off. It is not
abnormal.
(57)
Allow approx. 10 minutes pause when the dynamic brake is activated during high-speed running.
(58)
Resistor is damaged and the dynamic brake might not work when using it under more critical operating
condition.
Capacitance of the capacitors of power supply rectifier circuit drops over time. To avoid a secondary
problem due to a failure, replacement of capacitors is recommended at an interval of Abt imately 5
years. Commission the manufacturer or sales agency authorized by the manufacturer to replace the
parts.
Be sure to read operating manual (safety guide) that shipped with product before use.
