Analog Input Adjustment (C081); Start/End Frequency Setting For External Analog Input (A011 To A015) - Hitachi NES1-004SB Quick Reference Manual

Chapter 7 Explanation of Functions
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

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

Setting of the rate of the end frequency to the
external frequency command (0 to 10 V/0 to 20 mA)
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".
0 Hz
0 Hz is output as the output frequency while the
start-frequency rate is 0% to the value set as
"A013/A163".
