Commissioning
The following points should be checked or completed:
• Remove all securing, auxiliary and installation tools from the danger area.
• Check that the lift machine is used for its intended purpose and that the permissible ambient conditions are
met.
• Check that the lift machine is properly fastened.
• Are all bolts tightened with the specified torque and secured?
• Check the motor connection, especially the earthing.
• Check that the temperature monitoring devices are properly connected and functioning.
• Check that the brakes are properly connected and that the brake monitoring switches are functioning
properly.
• Is the measuring system properly connected?
• Check that the offset value indicated on the measuring system agrees with the value set on the converter.
• Check the proper functioning of the brake; perform a braking test using one partial brake.
• Is the rope slip-off guard properly tightened and adjusted?
Half-load test
An initial function test of the motor and the brake, together with the converter, should be performed before
the ropes are put in place.
If the motors are being operated at no shaft load (no ropes put in place) for an extended period of time,
abnormal noise may occur resulting from the bearing type used.
If the motor winding is short-circuited with the control system deactivated, a speed-dependent braking
torque will be produced, even at low speeds. Therefore, the short-circuiting should be deactivated during the
half-load test. It is imperative for it to be reactivated after the test.
