P0.10 Max output voltage
Range: 110~480V【Inverter rated】
Note:
Basic Frequency F
BASE
: Basic operating frequency is the Min output frequency
when the output voltage of inverter is equal to rated voltage U
N.
Usually, the motor
rated frequency can be treated as basic frequency. The changing range of basic
frequency F
BASE
of this series inverter is from 0.10 to 400.0Hz. Normally, F
BASE
is
selected based on motor rated frequency. In some special state, F
BASE
can be set
according to application needed. But at this time, the V/F characteristics of the load
and its contributed need must be considered. As shown in Fig. 5-0-1

Max frequency F
MAX:
This setting is the max frequency allowed to be output of this
series inverter. If reference is bigger than rated value of drive equipment, the motor
and equipment may be damaged.
Frequency upper limit f
H
is the highest frequency that inverter allowed to work. In
addition, frequency lower limit f
L
is the lowest. Setting frequency upper limit and
frequency lower limit, can automatically ensure that the output frequency is’ not
higher than frequency upper limit and not lower than frequency lower limit. This
function usually used to guarantee motor working in allowed frequency, to avoid
mistake action or mechanism or inverter backfire. It is especially useful in avoid
low-speed or over-speed. See P2.04.
Max output voltage is output voltage when the inverter runs at basic frequency.
Usually it is the rated input voltage of motor, which is marked on the nameplate of
motor.
P0.11 Step length of digital encoder
regulation
Range: 0~250* (0.01Hz|1rpm) 【0】
Note:
This parameter is effective for reference frequency and rotate speed of surveillance
state online regulating.
