Wiring of control circuit

(1) Control circuit terminal layout
(2) Common terminals of the control circuit (SD 5, SE)
Terminals SD, 5, and SE are all common terminals (0V) for I/O signals and are isolated from each other. Do not
earth(ground) these terminals.
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, STOP, RH, RM, RL, JOG, RT, MRS, RES,
AU, CS) and frequency output signal (FM).
The open collector circuit is isolated from the internal control circuit by photocoupler.
Terminal 5 is a common terminal for frequency setting signal (terminal 2, 1 or 4) and analog output terminal AM.
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, SU, OL, IPF, FU).
The contact input circuit is isolated from the internal control circuit by photocoupler.
(3) Signal inputs by contactless switches
The contacted input terminals of the inverter (STF, STR, STOP,
RH, RM, RL, JOG, RT, MRS, RES, AU, CS) can be controlled
using a transistor instead of a contacted switch as shown on the
right.
