wigwag-style control—without the necessity of providing independent forward
and reverse input signals—see rottle Type 4.
If the total resistance between Pins 14 and 16 is greater than 7.5 kΩ, the
controller’s 4.4 V upper fault limit will be exceeded and the controller output
will be disabled. is provides broken wire protection, and also serves as an
indication that the potentiometer’s nominal value has increased and the pot
needs to be replaced.
0–5V, 3-Wire Potentiometer, Current Source,
and Electronic Single-Ended Throttles (“Type 2”)
With these throttles (“Type 2” in the programming menu) the controller looks
for a voltage signal at the wiper input (Pin 15). Zero speed will correspond to
0V and full speed to 5 V. A 3-wire pot, voltage source, voltage sensor, or current
source can be used with this throttle type. e wiring for each is slightly dierent.
0–5V rottle
Two ways of wiring the 0–5V throttle are shown in Figure 6. e active range
for this throttle is from 0.2V (at 0% rottle Deadband) to 5.0 V (at 100%
rottle Max), measured relative to B-.
