Motor insulation test
Perform the insulation test when the motor is used for the first time
,
or when it is
reused after being stored for a long time
,
or in a regular check
-
up
,
in order to prevent
the poor insulation of motor windings from damaging the AC drive
.
The motor must be
disconnected from the AC drive during the insulation test
.
A 500
-
V mega
-
Ohm meter is
recommended for the test
.
The insulation resistance must not be less than 5 M
Ω.

Thermal protection of motor
If the rated capacity of the motor selected does not match that of the AC drive
,
especially when the AC drive
'
s rated power is greater than the motor
'
s
,
adjust the motor
protection parameters on the operation panel of the AC drive or install a thermal relay
in the motor circuit for protection
.

)
Running at over 50 Hz
The AC drive provides frequency output of 0 to 3200 Hz
(
Up to 300 Hz is supported if
the AC drive runs in CLVC and SFVC mode
).
If the AC drive is required to run at over
50 Hz
,
consider the capacity of the machine
.
6
)
Vibration of mechanical device
The AC drive may encounter the mechanical resonance point at some output
frequencies
,
which can be avoided by setting the skip frequency
.
7
)
Motor heat and noise
The output of the AC drive is pulse width modulation
(
PWM
)
wave with certain harmonic
frequencies
,
and therefore
,
the motor temperature
,
noise
,
and vibration are slightly
greater than those when the AC drive runs at power frequency
(
50 Hz
).
