Control circuit specifications
Wire removal
(3) 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, RL) and 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 speed setting signals (terminal 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.
3) Insert the wire into a socket.
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 screw driver, and insert the
wire.
NOTE
When using a stranded wire without a blade terminal, twist enough to avoid short circuit with a nearby terminals or
wires.
Place the flathead screwdriver vertical to the open/close button. In case the blade tip slips, it may cause to damage of
drive unit or injury.
Pull the wire with pushing the open/close button all the
way down firmly with a flathead screwdriver.

NOTE
Pulling out the terminal block forcefully without pushing
the open/close button all the way down may damage the
terminal block.
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 292
for the flathead drivers available on the
market.
Place the flathead screwdriver vertical to the open/close
button. In case the blade tip slips, it may cause to dam-
age of drive unit or injury.
