Description
Select whether or not to enable the
RTS (request-to-send) communica-
tions control function.
0: RTS control enabled
1: RTS control disabled (available to
1-to-1 RS-422 communications
only)
Sets the code to automatically set the
constants for energy-saving control.
0 to 10: 200-V AC, 0.1- to 4.0-kW
motor
20 to 30: 400-V AC, 0.1- to 4.0-kW
motor
These parameters prevent the motor
from over excitation due to voltage
changes during energy-saving con-
trol.
Sets the upper limit of output voltage Sets the upper limit of output voltage
as a percentage at each frequency
based on the rated motor voltage as
100%.
* Normally, the default settings do
not need to be changed.
Sets the detection width of power that
sets the Inverter into probe operation.
Sets the width as a percentage based
on the power to be detected as 100%.
* Normally, the default setting does
not need to be changed.
* The Inverter will operate with a
power detection width of 10% if the
value is set to 0.
Sets the filter time constant of the
power detection block of the Inverter
operating in probe operation.
Filter time constant (ms) = Set value
in n162 x 4 (ms)
* Normally, the default setting does
not need to be changed.
* The Inverter will operate with a
time constant of 20 ms if the value
is set to 0.
Sets the rate by which PID control
value is multiplied for PID control.
* Normally, the default setting does
not need to be changed.
