The R
NF
pin voltage with respect to the torque command
(E
C
) is as follows:
Torque command
The I / O gain (G
EC
) from the E
C
pin to the R
NF
pin (output
current) is determined by the R
NF
detector resistor.
G
EC
= 0.255 / R
NF
[A / V]
The torque limit current I
TL
is given by:
I
TL
= 0.35 / R
NF
[A]

Reverse rotation detection function
The reverse detection circuit construction is shown in
Fig.11.
(
1) Forward (E
C
< E
CR
)
The phase relationship between the Hall input signals
H2 and H3 becomes as shown in Fig.9, and the re-
verse rotation detection circuit does not operate.
(
2) Reverse (E
C
> E
CR
)
The phase relationship between the signals H
2
and
H
3
is opposite that for forward operation, and the re-
verse rotation detection circuit operates. The output
goes OFF, and becomes open circuit.
