Example 3: This example is used by the industry for operating the ac motor drive. The goal
is to have the set potentiometer equals to 10Hz when rotating to the far left. In other
words, when activating, the lowest output of the ac motor drive has to be 10Hz.
Other frequencies can be adjusted by the industry freely.
60Hz
P.38=60Hz Max operation frequency
P.192=0V, P.193=8.33V The minimum/maximum
input positive voltage of terminal 2-5
P.194=16.7%, P.195=100% The setting
corresponding to the minimum/maximum positive
voltage of terminal 2-5
P.510=16.7%, P.511=100% The setting
corresponding to the minimum/maximum negative
voltage of terminal 2-5
P.512=0V, P.513=8.33V The minimum/maximum
input negative voltage of terminal 2-5
P.194 = P.510 = 10Hz / 60Hz * 100
P.193 = P.511 = 10V * (100.0

Example 4: This example is also frequently used by the industry. The comprehensive
usage for all domain of the potentiometer setup elevates the flexibility.
P.38=60Hz Max operation frequency
P.192=0V, P.193=10V The minimum/maximum
input positive voltage of terminal 2-5
P.194=16.7%, P.195=100% The setting

voltage of terminal 2-5
P.510=16.7%, P.511=100% The setting
corresponding to the minimum/maximum negative
voltage of terminal 2-5
P.512=0V, P.513=10V The minimum/maximum
input negative voltage of terminal 2-5
P.139 = 0% The bias rate of 2-5 voltage signal

minimum/maximum positive voltage of terminal 2-5
P.510=0%, P.511=50% The setting corresponding to the
minimum/maximum negative voltage of terminal 2-5

Example 6:
This example is recommended to avoid using a signal that is less than 1V to
set up the operation frequency of the AC motor drive under an unfavorable
application environment, so that the anti-noise interference effect will be better.
