mounted on the output side, they shall be removed, otherwise, the drive would trip for
fault or the parts would be damaged, because output voltage of drive is the type of
impulse wave. In addition, on the output side, it is suggested that air switch and
contactor would not be installed either, shown as diagram 1-4. (If the switch unit has
to be mounted on the side of output, the output current of drive must be zero when the
switch operates.)

1.3.6 Run at over 50Hz.
If the drive has to run at over 50Hz, the applicable speed range of motor bearing
and mechanical equipment must be guaranteed in addition to considering the
vibration and noise of motor, and please inquire before drive runs.
1.3.7 Electronic heat protection value of motor
When a motor chosen is applicable, the drive can provide the motor with heat
protection. If the motor doesn’t match with the rated capacity of drive, the protection
value must be adjusted or other protection measures must be taken, to guarantee the
motor runs safely.
1.3.8 Altitude and derating use
If the drive runs in area of over 1000m altitude, it must be de-rated by reason that
the heat radiation of drive gets poor for rarefied air. Diagram 1-5 shows the relation
between rated current of drive and altitude.
