Parameter Frequency setting by analog input (terminal 2, 4)
FR-D700 SC EC 6 - 147
6.15 Frequency setting by analog input (terminal 2, 4)
6.15.1 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: 0–10V, 0–5V oder 0/4–20mA
●
Suppress motor reversing
The above parameters can be set when Pr. 160 = 0.
