Parameter Factory Setting Description

THROTTLE MENU
Type 7 7
The 1212 controller can accept inputs from both 5k, 3-wire
pot throttles and voltage throttles. Set the throttle type param-
eter to match the throttle used in your application.
5k, 3-wire pot throttles
0 = wigwag
1 = inverted wigwag
2 = single-ended; neutral when wiper at PotLow
3 = inverted single-ended; neutral when wiper at PotHigh
4 = unipolar.
Voltage throttles
5 = wigwag
6 = inverted wigwag
7 = single-ended; neutral when wiper PotLow
8 = inverted single-ended voltage; neutral when wiper
PotHigh
9 = unipolar
PotHigh 5V 5V
Sets the maximum voltage for voltage throttles (Types 5–9).
For 5k, 3-wire pot throttles, PotHigh is determined by the
throttle itself.)
PotLow 0V 0V
Sets the maximum voltage for voltage throttles (Types 5–9).
For 5k, 3-wire pot throttles, PotLow is determined by the
throttle itself.)
Neutral Deadband 5% 5%
Sets the throttle range the controller interprets as neutral.
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.
Throttle Max 90% 90%
Sets the pot wiper voltage required to produce 100% controller
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.
HPD ON ON
When programmed On, vehicle drive is inhibited if a throttle
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.
Speed Limit Pot OFF OFF
This parameter is used to enable/disable the speed limit pot. If
no speed limit pot is used, set Speed Limit Pot to Off.
