7.4.5 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/OI-L terminal: 0 to 10 V or 0 to 20mA
- VR : volume of NES1-OP, OPE-SR/SRmini

Externally input start frequency
The frequency set as "A011/A161" is output as the
output frequency while the start-frequency rate is 0%
to the value set as "A013
/
A163".
01
0 Hz
0 Hz is output as the output frequency while the
start-frequency rate is 0% to the value set as
"A013
/
A163".
If the voltage of the signal to be input to the O-L terminal is 0 to 5 V, specify 50% for "A014".
