Analog Inputs - YASKAWA E7N Technical Manual

Analog Inputs

The Drive has two analog input terminals for use as auto mode speed command (terminals A1 & A2) and feedback (terminal
A2) input.

Control Circuit Analog Input Terminals on PCB A2
All control inputs are landed on TB1 through TB5 on PCB A2.
TB3-3 is an analog input terminal and may be connected to either Drive terminal A1 or Drive Terminal A2, to maximize input
flexibility, using DIP switches S1-3 and S1-4. The factory default is TB3-3 connected to Drive terminal A2. With this
connection, the input signal level can be either 0 to 10 VDC or 4 to 20 mA. The signal level selection is controlled by DIP
switch S1-2 and Drive parameter H3-08.
TB5-9 is also an analog input terminal, it is always connected to Drive terminal A2.
See Table 2.8, Figure 2.5 and Schematic Diagram DS.E7N.01 for clarification of the analog input configuration and applica-
tions.
