Chapter 5 ParametersVFD-S Series

Explanations:

d0 Parameter Disable:

Enter value (d0) to disable any Multi-Function Input Terminal: M1 (Pr.4-04), M2 (Pr.4-05), M3 (Pr.4- 06), M4 (Pr.4-07) or M5 (Pr.4-08).

NOTE

The purpose of this function is to provide isolation for unused Multi-Function Input Terminals. Any unused terminals should be programmed to d0 to insure they have no effect on drive operation.

d1 Two wire operation: Restricted to Pr.4-04 and external terminals M0, M1.

FWD/STOP

M0 "Open": Stop, "Close": FWD Run

REV/STOP

M1 "Open": Stop, "Close":REV Run

GND

d2 Two wire operation: Restrict to Pr. 4-04 and external terminals M0, M1.

M0 "Open": Stop, "Close": Run

RUN/STOP

M1 "Open": FWD, "Close":REV

REV/FWD

GND

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
