„ Control Circuit Input Terminals
Table 8 lists the input terminals on the drive. Text in parenthesis indicates the default setting for each multi-function
input.
Table 8 Control Circuit Input Terminals
Terminals A1 and A2 can accept a voltage signal to supply the speed reference to the drive. Table 9 shows the parameter
settings and voltage levels required for each terminal.

Type
<1> Setting jumper S3 for an external power supply makes the wire jumper between terminals H1, H2, and HC ineffective. Remove the wire jumper
and connect an external power supply that can supply terminals H1, H2, and HC continuously.
