CWH
The first basic parameter “CWH” (Wizard function) is displayed.

Press either the key or the key to adjust the meter.
The meter reading will change at this time but be careful because there
will be no change in the inverter's digital LED (monitor) indication.

The adjustment is complete. HO and the frequency are displayed
alternately.

Adjusting the meter in inverter stop state
• Adjustment of output current (HOUN=)
If, when adjusting the meter for output current, there are large fluctuations in data during adjustment,
making adjustment difficult, the meter can be adjusted in inverter stop state.
When setting HOUN to for fixed output 1 (100% output current), a signal of absolute values will be
output (inverter's rated current = 100%). In this state, adjust the meter with the HO (Meter adjustment)
parameter.
Similarly, if you set HOUN to for fixed output 2 (output current at 50%), a signal that is sent out when
half the inverter's rated current is flowing will be output through the FM terminal.
After meter adjustment is ended, set HOUN to (output current).
• Adjustment of other items (HOUN=, to , )
If parameter HOUN is set to : Fixed output 3 (Other than the output current: 100%), a signal that is
sent out when HOUN is set to , to , (100%) will be output through the FM terminal.
100% standard value for each item is the following:
HOUN
=, ,
: Maximum frequency (HJ)
HOUN
=,
: 1.5 times of rated voltage
HOUN
=,
: 1.85 times of rated power
HOUN
=,
: 2.5 times of rated torque
HOUN
=,
: Rated load factor
HOUN
=,
: Maximum input value
HOUN
=
: FA51=1000
[Hint]
It's easier to make the adjustment if you
push
and hold for several seconds.
