Parameter Frequency setting by analog input (terminal 2, 4)
FR-E700 SC EC/ENE 6 - 177
6.16 Frequency setting by analog input (terminal 2, 4)
6.16.1 Analog input selection (Pr. 73, Pr. 267)
You can select the function that switches between forward rotation and reverse rotation according to
the analog input terminal specifications and input signal.
The following settings are possible:
●
Select reference voltages and currents: 0–10 V, 0–5 V or 0/4–20 mA
●
Suppress motor reversing
The above parameters can be set when Pr. 160 "User group read selection" = 0.
