1) | Valid for all motors with a shaft height greater than 56 mm. |
2) | The boundary conditions in section Power dissipation 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. |
