0–10V Input Voltage Setting Details
In.01 Freq at 100%
at the maximum input voltage when a
potentiometer is connected to the control terminal block. A frequency set with
code In.01 becomes the maximum frequency only if the value set in code Ao.07
(or Ao.13) is 100(%).
• Set code In.01 to 40.00 and use default values for codes Ao.01–Ao.09. Motor
will run at 40.00Hz when a 10V input is provided at V3
• Set code Ao.07 to 50.00and use default values for codes In.01, Ao.01–Ao.09.
Motor will run at 30.00Hz (50% of the default maximum frequency–60Hz)
when a 10V input is provided at V3.
Configures the inverter to monitor the input voltage at V
Ao.03 V3 Filter
Filter may be used when there are large variations between
frequencies. Variations can be mitigated by increasing the time constant, but this
will require an increased response time.
The value t (time) indicates the time required for the frequency to reach 63% of
the reference, when external input voltages are provided in multiple steps.

These parameters are used to configure the gradient level and offset values of the
Output Frequency, based on the Input Voltage.
