Control circuit specifications
3) Insert the wire into a socket.
When using a stranded wire without a blade terminal, twist enough to avoid short circuit with a nearby terminals or
Place the flathead screwdriver vertical to the open/close button. In case the blade tip slips, it may cause to damage of
inverter or injury.
Pull the wire with pushing the open/close button all
the way down firmly with a flathead screwdriver.
Control circuit common terminals (SD, 5, SE)
Terminals SD, SE and 5 are common terminals for I/O signals.(All common terminals are isolated from each other.) Do not
earth them. Avoid connecting the terminal SD and 5 and the terminal SE and 5.
Terminal SD is a common terminal for the contact input terminals (STF, STR, RH, RM, AU) and the pulse train output terminal
(FM). The open collector circuit is isolated from the internal control circuit by photocoupler
Terminal 5 is a common terminal for the frequency setting signals (terminals 2 or 4). It should be protected from external noise
using a shielded or twisted cable.
Terminal SE is a common terminal for the open collector output terminal (RUN). The contact input circuit is isolated from the
internal control circuit by photocoupler.
When using a single wire or a stranded wire without a blade terminal, push an
open/close button all the way down with a flathead screwdriver, and insert the wire.
Pulling out the terminal block forcefully without pushing
the open/close button all the way down may damage the
Use a small flathead screwdriver (Tip thickness: 0.4mm/
tip width: 2.5mm).
If a flathead screwdriver with a narrow tip is used,
terminal block may be damaged. Refer to page 344 for the
flathead drivers commercially available.
Place the flathead screwdriver vertical to the open/close
button. In case the blade tip slips, it may cause to
damage of inverter or injury.
