Commissioning
The following points should be checked or completed:
• Check that all performance and application data specified on the name plate of the machine are consistent
with your application.
• Have all securing, auxiliary and installation tools been removed from the danger area?
• Check that the lift machine is being used for its intended purpose – comply with the permissible ambient
conditions.
• Check that the lift machine has been properly fastened with the fastening bolts – have the bolts been tight-
ened to the specified torque and secured?
• Has the motor been properly connected, including the motor protection? Has the PE terminal been properly
connected? Is the potential equalisation with the machine frame ensured?
• Check the proper functioning of the temperature monitoring devices (e.g. by interrupting the temperature
monitoring circuit).
• Check the brake connection and the proper functioning of the brake monitoring switches.
• Ensure that the brake operates correctly; perform a brake test using one partial brake.
• Has the measuring system been properly connected?
• Check that the offset value indicated on the measuring system agrees with the value set on the inverter.
• Is the rope slip-off guard properly tightened and adjusted?
An initial function test of the motor and the brake, together with the inverter, 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.
