NOTE
• Terminals SD, SG and SE are common terminals for I/O signals. (All common terminals are isolated from each other.) Do
not earth (ground) these terminals. Avoid connecting terminals SD and SG and terminals SE and SG.
• Terminal SD is a common terminal for the contact input terminals (STF, STR, RH, RM, RL, MRS, and RES) and the pulse
train output terminal (FM). The open collector circuit is isolated from the internal control circuit by photocoupler.
• Terminal SG is a common terminal for the frequency setting signal (terminal 2 or 4) and RS-485 communication. Use a
shielded or twisted cable to protect the terminal from external noise.
• Terminal SE is a common terminal for the open collector output terminals (RUN and FU). The contact input circuit is isolated
from the internal control circuit by photocoupler.
