Standard Connection Diagram 1; Standard Connection Diagram - Sink (Negative) (Common:cc) - Toshiba TOSVERT VF-nC3E Instruction Manual

2.2.1
This diagram shows a standard wiring of the main circuit.
2
Main circuit power supply
3ph-400V class: three-phase 380-460V
*1: VFNC3C-4004P, 4007P models don't VFNC3E-4004P, 4007P
have the PA/+ and the PB terminals
and cannot be used with Braking
resistor.
*2: When using the OUT output terminal in
sink logic mode, short the NO and CC
terminals.
*3: When external potentiometer is connected
by using P5 terminal, set the parameter
f109=3.
*4: When VI terminal is used as a logic
input terminal, refer to page B-12.
5: Calibration is needed before using the meter.
