Setup Of External Speed Command (Analog Signal - Toshiba TOSVERT VF-AS1 Instruction Manual

7.3

Setup of external speed command (analog signal)

Function of analog input terminals can be selected from four functions (external potentiometer, 0 to 10Vdc, 4 (0) to
20mAdc, -10 to +10Vdc). The selective function of analog input terminals gives system design flexibility.
⇒ Refer to Section 6.28 for fine adjustment of analog setting signal and output frequency.
