<14> Default setting value is dependent on the motor code set to E5-01.
<17> Default setting is dependent on the speed estimation method selection (n8-72) as follows:
50.0 when n8-72 = 0
150.0 when n8-72 = 1
<18> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.

There is normally no need to change this parameter from the default value.
Sets the proportional gain for Speed Estimation.
V/f V/f w/PG
OLV/PM AOLV/PM
There is normally no need to change this parameter from the default value.
Sets the method to be used for estimating the speed.
0: Conventional method
1: A1000 method
Note: This parameter is not available with models CIMR-A4A0930 and 4A1200.

Sets the current to determine polarity for the initial polarity calculation as a percentage of the
motor rated current.
100% = Motor rated current
Note: If an "Si" value is listed on the nameplate for a YASKAWA motor, n8-84 should be set to
"Si" value  2.
All Modes
Switches the display after the power has been turned on. When using an LED operator, pressing
the up arrow key will display the following data: frequency reference  rotational direction 
output frequency  output current  output voltage  U1-.
(This is done by entering the 1 part of U1-. Certain monitors are not available in some
control modes.)
All Modes
o1-02 selects the information that is displayed when the power is turned on.
1: Frequency reference (U1-01)
2: Direction
3: Output frequency (U1-02)
4: Output current (U1-03)
5: User-selected monitor (set by o1-01)
All Modes
Sets the units the drive should use to display the frequency reference and motor speed monitors.
0: 0.01 Hz
1: 0.01% (100% = E1-04)
-1
2: min (calculated using the number of motor poles setting in E2-04, E4-04, or E5-04)

All Modes
Sets the brightness of the LCD operator (option).
All Modes
These settings define the display values when o1-03 is set to 3.
o1-10 sets the display value that is equal to the maximum output frequency.
o1-11 sets the position of the decimal position.
