Note: Multi-function Input Terminal M0 does not have its own parameter designation. M0
must be used in conjunction with M1 to operate two and three wire control.
d3: Three Wire Control:
Restricted to Pr.4-04 control terminals M0, M1, M2.
STOP
RUN
RUN/FWD
M0 Run command, Runs when "close"
M2 Stop command, stops when "Open"
M1 REV/FWD Run selection
"Open": FWD Run
"Close": REV Run
GND
Note: When value d3 is selected for Pr. 4-04, this will over ride any value entered in
Pr.4-05, since Pr.4-05 must be used for three wire control as shown above.
d4, d5 External Faults:
Parameter values d4, d5 programs Multi-Function Input Terminals: M1 (Pr.4-04), M2
(Pr.4-05) or M3 (Pr.4-06) to be External Fault (E.F.) inputs.
GND
E.F.(N.O.)

Mx "Close": Operation available.
Mx "Open":Operation available.
When an External Fault input signal is received, the AC drive will stop all output and
display
³ E.F. ´ on Digital Keypad, the motor will free run. Normal operation can resume
after the External Fault is cleared and the AC drive is reset.
d6 External Reset:
Parameter value d6 programs a Multi-Function Input Terminal: M1 (Pr.4-04), M2 (Pr.4-05)
or M3 (Pr.4-06) to be an External Reset.
