Maximum Frequency; Analog Input (O, O2, Oi) - Omron 3G3RX User Manual

Maximum Frequency

•Set the maximum value of the output frequency.
•The value set here is the maximum value (e.g.,10 V in the range from 0 to 10 V) of the external
analog input (frequency reference).
•The maximum Inverter output voltage from base to maximum frequencies is the voltage set in AVR
voltage selection A082.
•The Inverter cannot output voltage beyond that of the incoming voltage.
Parameter No. Function name
A004 Maximum frequency
A204 *2nd maximum frequency
A304 *3rd maximum frequency

* To switch to the 2nd/3rd control, allocate 08 (SET)/17 (SET3) to the desired multi-function input and then turn it
on.

Analog Input (O, O2, OI)

•The Inverter has three types of external analog input terminals.
O-L terminal: 0 to 10 V
OI-L terminal: 4 to 20 mA (current input)
O2-L terminal: -10 to 10 V (voltage input)
•Below are the settings for this function.
