Change
the

using
the
OL.LMT
(VR).
¢ | Counterclockwise:
50~80%

For

be
100%.
The
overload
limit
level
variable
resistor
(OL.LMT)
is
located
on
PC
board
when
the
inverter
terminal
cover
is
removed.
Standard
setting
is approx.
125%.
The
slip
compensation
allows
to
reduce
the
natural
speed
loss
of
the asynchronous
motor
due
to
increased
load.
In the range
under
condition
of V/F constant
and
above
15Hz,
speed
accuracies
of approx.
1.5% ny can be
achieved
without
tacho
generator
feedback.
Turning
the
"SL.COM"
(VR)
clock-
wise,
reduces
the slip.
