Symbol Name Function Specifications
Input 24VDC Internal 24-V power sup-
ply The 24-VDC power supply input for
Inverter control circuits. Do not use this
power supply for any other purpose. Photocoupler
(24 V DC, 5 mA
per input)
SS0 Multi-step speed refer-
ence 0 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.)
SS1 Multi-step speed refer-
ence 1
STF Forward/stop command Executes forward operation.
STR Reverse/stop command Executes reverse operation.
SC External power supply
common Common terminal for when internal
24-V power supply is not used.
Output ALM (+) Alarm output Turns ON when an alarm occurs. Open collector
(30 V DC, 50 mA
max.)
