Description
Function
The 24-VDC power supply input for
Inverter control circuits. Do not use this
power supply for any other purpose.
Executes multi-step speed reference in
combination with SS0 and SS1 when
P11 (Frequency reference selection) is
set to MSP (multi-step speed refer-
ence). (See note.)
Executes forward operation.
Executes reverse operation.
Common terminal for when internal
24-V power supply is not used.
Turns ON when an alarm occurs.
Turns ON when the operating status
selected in P12 (Multi-function output
selection) is reached.
