●
After installation and electrical connections of the traction machine are finished, check
carefully whether the fixing and electrical connection of the machine is reliable and
correct.
●
After checking and no errors are found, before suspending the car and
counterweights, enter related parameters of the machine into the frequency converter,
and enable the frequency converter to supply power to the motor at no load. In this
case, the motor and frequency converter should be in self-learning status. The
frequency converter reads out related parameters of the motor and relative position
values of magnetic fields of the stator and rotor of the motor.
●
After self-learning, supply power in non-load state to check whether the self-learning
is completed correctly. After confirmation, suspend the car and counterweights.
During commissioning, the learning had better be carried out three or four times.
Check if the nonconformance of magnetic-field position readings of the stator and
rotor is very slight.
●
As different users select the frequency converter from different suppliers and types,
the actual operation and commissioning should be conducted strictly according to the
operation manuals supplied by the frequency converter manufacturer. If there are any
problems during the commissioning, please contact the frequency converter
manufacturer in time.
●
In order to reduce the braking noise before leaving factory, there is slight gap between
the brake shoe and brake wheel rim. During the first self-learning, friction exists and
the state is not real no-load state. Therefore, after first learning, run the machine at no
load for 3 min or longer before a second learning can be started. Or otherwise, the
current on loads will be increased by 10～15%

Brake：When the elevator is leveling, de-energized or in inspection of failure, the electromagnet is
under de-energized state, the armature pushes the disc under the function of spring, and it brakes
by the friction between the friction disc, armature and electromagnet core. As the friction disc and
