Cautions when using low temperature environment.
When an ambient temperature is low, since the load torque may increase by oil
seal or viscosity increment of grease used in the gearhead, the output torque
may decrease or overload alarm may generate. However, as time passes, the oil
seal or grease is warmed up, and the motor can be driven without generating
and overload alarm.
Noise elimination measures
Porovide noise elimination measures to prevent a motor or drive malfunction
casued by external noise. For more effective elimination of noise, use a shielded
I/O cable or attached ferrite core if a non-shielded cable is used.
• Repairing and checking
Warning
Stop to supply power to the main circuit and wait sufficient time before
checking or repairing this Ezi-SPEED
Electricity remaining in the condenser may cause of electric shock.
Do check and repair after a minute.
Do not change cabling while power is being supplied.
Otherwise, the user may get injured or the product and machine may get
damaged.
Do not reconstruct the Ezi-SPEED
Otherwise, an electric shock may occur or the product and machine get damag
ed. And the reconstructed product cannot get after service.
Conduct insulation resistance measurement or dielectric strength test
separately on the motor and the drive.
Conducting the insulation resistance measurement or dielectric strength test
with the motor and drive coneected may result in damage to the product.
Grease prevent measures
A small amount of grease may come out from the gearhead. If there is concern
over possible environmental damage resulting from the leakage of grease,
install an oil tray or similar prevention deivce. Oil leakage may lead to problem
in customer’s equipment or products.
