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.

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.
