Please dispose the inverter as industrial
wastes.
1.2.13 Adaptable Motor
1) The standard adaptable motor is
four-pole squirrel-cage asynchronous
induction motor. If such motor is not
available, be sure to select adaptable motors
according to the rated current of the motor.
In applications where drive permanent
magnetic synchronous motor is required,
please consult our company;
2) The cooling fan and the rotor shaft of
the non-variable-frequency motor adopt
coaxial connection. When the rotating speed
is reduced, the cooling effect will be reduced.
Therefore, a powerful exhaust fan shall be
installed, or the motor shall be replaced with
variable-frequency motor to avoid the over
heat of the motor.
3) Since the inverter has built-in standard
parameters of the adaptable motors, it is
necessary to perform motor parameter
identification or modify the default values so
as to comply with the actual values as much
as possible, or it may affect the running effect
and protection performance;
The short circuit of the cable or motor
may cause alarm or explosion of the inverter.
Therefore, please conduct insulation and
short circuit test on the newly installed motor
and cable. Such test shall also be conducted
during routine maintenance. Please note
that the inverter and the test part shall be
completely disconnected during the test.
