When setting parameters, refer to the instruction manual (applied) and understand instructions.

The inverter can be used to exercise process control, e.g. flow rate,
air volume or pressure.
The terminal 2 input signal or parameter setting is used as a set
point and the terminal 4 input signal used as a feedback value to
constitute a feedback system for PID control.

Pr.128 = "20, 21" (Measured value input)
The display language of the parameter unit (FR-PU07) can be
changed.
When using an FR-E500 series operation panel (PA02), the
frequency setting method can be switched using
Pr.146 Built-in
potentiometer switching .
The output current during inverter running can be detected and
output to the output terminal.
(1) Output current detection
(Y12 signal, Pr. 150, Pr. 151, Pr. 166, Pr. 167 )

The output current detection function can be used for
excessive torque detection, etc.

If the output during inverter running is the Pr.150 setting or
higher for the time set in Pr.151 or longer, the output
current detection signal (Y12) is output from the inverter's
open collector or relay output terminal.
(2) Zero current detection (Y13 signal,
Pr. 152, Pr. 153
)

If the output during inverter running is the Pr.152 setting or
lower for the time set in Pr.153 or longer, the zero current
detection signal (Y13) is output from the inverter's open
collector or relay output terminal.
 Parameter which can be read from the operation panel and
parameter unit can be restricted.
In the initial setting, only the simple mode parameters are displayed.
