The o parameters are used to set up the digital operator displays.

o1: Digital Operator Display Selection
n8-69
(65DH)
Speed Calculation Gain
There is normally no need to change this parameter from the default value.
Sets the proportional gain for Speed Estimation.
Default: 1.00
Min: 0.00
Max: 20.00
312
n8-72
(655H)
Speed Estimation Method
Selection
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.
Default: 1
Min: 0
Max: 1
313
n8-84
(2D3H)
Polarity Judge Current
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.
Default: 100%
Min: 0%
Max: 150%
313
<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.

o1-01
(500H)
<10> Default setting is determined by the control mode (A1-02).
<36> Default setting value is determined by the digital operator display selection (o1-03).
Drive Mode Unit Monitor
Selection
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.)
Default: 106 (Monitor
