4.2.13 Frequency addition function
The frequency addition function allows you to add or subtract the value
specified as the frequency to be added (A145) to or from the frequency
value of a selected frequency command.
To use this function, assign function "50" (ADD) to an intelligent input terminal.
When the ADD terminal is turned on, the inverter performs the addition or subtraction of the value specified as
"A145".

Terminal function
Note 1: If the sign of the frequency value in the frequency command changes from minus (-) to plus (+), or vice versa,
as the result of frequency addition, the motor operation direction will be inverted.
Note 2: When the PID function is used, the frequency addition function can apply to PID target data. (In such cases,
the data display by function "A145" is in percentage [in steps of 0.01%]).
4.2.14 Start/end frequency setting for external analog input
The start/end frequency setting function
allows you to set the inverter output frequency
in relation to the external analog inputs
(frequency commands) via the following
terminals:
O-L terminal: 0 to 10 V
OI-L terminal: 4 to 20 mA
O2-L terminal: -10 to +10 V

If the voltage of the signal to be input to the O-L terminal is 0 to 5 V, specify 50% for "A014".

Externally input start frequency
The frequency set as "A011" or "A101" is output as the
output frequency while the start-frequency rate is 0% to
the value set as "A013" or "A103".
0 Hz
0 Hz is output as the output frequency while the
start-frequency rate is 0% to the value set as "A013" or
"A103".
