5)
Vertical, motor stands on the machine (IM3031)
Storage and transport conditions
Storage temperature
-20 to 60°C
Relative humidity during storage
Max. 90%, non-condensing
Transport temperature
-20 to 60°C
Relative humidity during transport
Max. 90%, non-condensing
1)
Valid for all motors with a shaft height greater than 56 mm.
2)
The boundary conditions in section
"Power dissipation" on page 25
must be taken into account.
3)
Continuous operation of the servo motors at an ambient temperature of 40°C to max. 45°C is possible, but this results in premature aging.
4)
Requirements that go beyond this must be arranged with B&R.
5)
With the IM3011 type of construction and installation (vertical, motor hangs on the machine) there is a risk that production fluids or oils will penetrate the
motor on the flange side. Motors or motor-gearbox combinations that should be used in this type of installation must therefore have at least IP65 protection
on the flange side.
