4.CONDITIONS FOR APPROVAL RELATED TO THE IEC60034 STANDARD SPECIFICATIONS FOR THE βiS SERIES B-65302EN/01
- 84 -
4.2.3 Protection Type (IEC60034-5)
Motor protection confirms to IP65. The Pulsecoder connector is
waterproof when engaged.
IP6x: Completely dust-proof machine
This structure completely prevents dust from entering the
machine.
IPx5: Sprinkle-proof machines
A sprinkle-proof machine shall not suffer inadvertent influence
when they are exposed to water sprinkled from nozzles at any
angle to the machine.
The conditions of the IPx5 type test are as follows:
Nozzle inside diameter...................................................φ6.3 [mm]
Amount of sprinkled water ............................. 12.5 [liters/minute]
Water pressure at the nozzle.............................................30 [kPa]
Sprinkle time per a surface of 1 m
2
................................1 [minute]
Minimum required time.................................. 3 [minutes]or more
Distance between the nozzle and machine .. Approximately 3 [m]
CAUTION
IPx5 evaluates machines for waterproofness in a
short-term test as described above, allowing
chances that the machines may get dry after the test.
If a machine is exposed to liquids other than water or
so continuously to water that it cannot get dry, it may
suffer inadvertent influence even if the degree of
exposure is low.
4.2.4 Cooling Method (IEC60034-6)
All models of the FANUC AC servo motor βis series use the fully-
enclosed natural cooling system. The IC code is IC410.
4.2.5 Mounting Method (IEC60034-7)
The motors can be mounted by the following methods.
IMB5:Flange mounting with the shaft facing sideways(from the rear)
IMV1:Flange mounting with the shaft facing upward(from the rear)
IMV3:Flange mounting with the shaft facing downward(from the rear)
