To the negative supply
input (0 V) of the speed
encoder
I = 100 mA
V = 0.5 V
We recommend the use of
screened cable for the
encoder wiring. Connect the
screen to this pin only along
with the negative supply.

Zin = 82 kΩ
(24V/36V and
36V/48V
models)
Zin = 100 kΩ
(24V/36V and

Suitable for potentiometers
in the range 500 Ω to 10 kΩ,
or voltage-output device
(e.g. Sevcon linear
accelerator)
0 to 5 V or 0 to 10 V.
Ensure that at least 0.5V
margin exists between the
maximum valid throttle and
the wire-off threshold
