It is possible to display the load speed such as
a
conveyor, instead
of
the motor. For this display,
it is necessary to
set
the unit of display which
meets the load's speed using the parameter unit.
0
Setting should
be
made for the load's speed at
MHz.
Notes:
1.
This sening is valid only for the
monitor mode using the parameter
unit. Parameters related with other
speed information such as Pr.1
should
be
set in units of
Hz.
2.
The motor speed is given by convert-
ing the output frequency. It does not
agree with the actual
motor
speed.
3.
Due to the restriction on the resolu-
tion
of
the set frequency, display in
the second place right
of
the decimal
point may differ from the set value.
