Description
pot throttles and voltage throttles. Set the throttle type param-
eter to match the throttle used in your application.
0 = wigwag
1 = inverted wigwag
2 = single-ended; neutral when wiper at PotLow
3 = inverted single-ended; neutral when wiper at PotHigh
4 = unipolar.
5 = wigwag
6 = inverted wigwag
7 = single-ended; neutral when wiper PotLow
8 = inverted single-ended voltage; neutral when wiper 

9 = unipolar
For 5k, 3-wire pot throttles, PotHigh is determined by the
throttle itself.)
For 5k, 3-wire pot throttles, PotLow is determined by the
throttle itself.)
Increasing the parameter setting increases the neutral range.
This parameter allows the neutral deadband to be defined
wide enough to ensure the controller goes into neutral when
the throttle is released.
output. Increasing the Throttle Max setting reduces the wiper
voltage required, and therefore reduces the stroke necessary
to produce full output. This feature allows reduced-range
throttle assemblies to be used.
command outside the neutral deadband is issued before the
controller is powered up. Drive will continue to be inhibited
until the throttle is returned to within the neutral deadband. If
the HPD fault is not cleared within 10 seconds, a wiring fault
is declared and a power cycle is required.
no speed limit pot is used, set Speed Limit Pot to Off.
