Check the following items:
a) Rotation direction
b) Whether rotation is smooth (whether there
is a motor buzzing noise or abnormal vi-
bration)
c) Whether acceleration and deceleration are
smooth
d) Whether the inverter cooling fan is rotating
(1.5kW or more)
If no abnormality is detected, check the item
again by increasing the frequency.
Even if the output from the inverter is stopped,
you will be get an electric shock when you touch
the main circuit terminals such as inverter output
terminals U, V and W if the voltage is supplied to
the main power supply input terminal.
The smoothing capacitor in the inverter has
been charged when the power is turned off and
it is not discharged immediately. Before touch-
ing the electric circuit, wait until at least five min-
utes have elapsed after power-off and the
charge lamp is off, indicating the voltage is al-
ready low.
After checking normality in the above trial run,
start operation.
WARNING
1. The STOP key is valid only when the func-
tion has been set.
Assign another switch to emergency stops.
Otherwise accidents could occur.
2. Operation starts suddenly if alarm reset is
done with an running signal input. Check
that no running signal is input before alarm
reset.
Otherwise accidents could occur.
CAUTION
Do not touch the heat sink.
Otherwise burns could occur.
