6-9
Note 2. These voltages are for the 200-V class; Double the voltage for 400-V class Inverters.
Note 3. The
default
setting depends on the Inverter
’
s capacity
. The default settings shown in the table
are for 200-V class, 0.4 to 1.5 kW Inverters.
Note 4. The default settings for E1-07 through E1-10 depend on the control mode. The default
set
-
tings shown in the table are for open-loop vector control.
Note 5. The four frequency settings must satisfy the following formula:
E1-04 (F
MAX
) ≥ E1-06 (F
A
) > E1-07 (F
B
) ≥ E1-09 (F
MIN
)
For flux vector control, make the settings as follows:
E1-04 (F
MAX
) ≥ E1-06 (F
A
) > E1-09 (F
MIN
)
Note 6. When
making the V/f characteristics a straight line, set the same value in
E1-07 (middle out
-
put
frequency) and E1-09 (minimum output frequency). In this case, parameter E1-08 (middle
output voltage) will be ignored.

D Adjusting Output Voltage
Adjust
the output voltage when you want to output
more torque at low speed, such as in an elevator
, or
when torque isn’t really necessary and you want to reduce the output voltage to save energy.
• When
generating more torque, gradually increase the voltage but do not exceed 100% of the Invert
-
er’s rated output current.
• When saving energy, decrease the voltage but do not cause stalling.
D Setting the Maximum Frequency
The
maximum frequency can be set from 50.0 to 400.0 Hz. Set this parameter in accordance with the
motor’s maximum rotational speed.
H Setting Motor Parameters
The motor parameters (function E2) will all be set automatically when auto-tuning is performed, so it
normally
isn’t necessary to set them manually
. Set these parameters manually if auto-tuning can’t be
completed properly. These parameters cannot be changed during operation.
Set the rated current (A) shown on the motor’s nameplate.
