Differential Current Input (Ai1+, Ai1-) - Toshiba TOSVERT VF-AS1 Instruction Manual

 Parameter
Title
f672 MON1 terminal meter selection
f673 MON1 terminal meter adjustment
f674 MON2 terminal meter selection
f675 MON2 terminal meter adjustment
f688
MON1 voltage/current output switching
f689
MON1 output gradient characteristic
f690
MON1 bias adjustment
f691
MON2 voltage/current output switching
f692
MON2 output gradient characteristic
f693 MON2 bias adjustment
Note1: When MON1 (MON2) setting is the voltage -10 - 10V output, f689 ( f692 ) setting is invalid
and the MON1 (MON2) gradient characteristics becomes the positive inclination.
Note2: When MON1 (MON2) setting is -10 - 10V voltage output, f672 ( f674 ) should be set the
signed output.

3.5. Differential current input (AI1+, AI1-)

The frequency command can be input from the differential current input AI1 and AI2
terminal current. Keep each of the terminal voltages from CC terminal from -10V to 10V,
and keep voltage under 5V between each terminal.
