Description
In.01 Freq at
100%
Configures the output frequency at the maximum analog input current.
The frequency set with In.01 becomes the maximum frequency when
the value set in In.56 is set to 100%.
In.50 I2 Monitor
Display the value of the input current at I2.
In.52 I2 Filter
In.52 is a low-pass filter (time constant) setting that can be applied to
the analog signal. Noise on the analog signal causes the inverter ouput
frequency to fluctuate. This setting filters the analog signal to provide a
clean input signal. Higher settings of the time constant filter will
decrease variations in inverter output frequency, however this slows
the response time of the inverter output when changing the I2 input
signal.
The In.52 value (t, time) indicates the time required for the output
frequency to reach 63% of the I2 input.

These parameters are used to configure the offset and gradient level
(slope) values of the analog input to the required inverter output.
• Set In.01 to 60.00 and use default settings for In.53 through In.56.
Motor will run at 60 Hz. when 20 mA input current is applied to the
I2 terminal.
• Set In.56 to 50.00 and use default settings for In.53 through In.55.
The motor will run at 30 Hz. when 20 mA input current is applied to
the I2 terminal.
