RANGE

0–9

The 1212 controller can accept inputs from both 5kΩ, 3-wire pot throttles

and voltage throttles. Set the throttle type parameter to match the throttle

used in your application.

5k Ω , 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

Note: If Throttle Type 5–9 is used, see note on page 8.

3–5 V

Sets the maximum voltage for voltage throttles (Types 5–9).

(For 5kΩ, 3-wire pot throttles, PotHigh is determined by the throttle itself.)

0–2 V

Sets the minimum voltage for voltage throttles (Types 5–9).

(For 5kΩ, 3-wire pot throttles, PotLow is determined by the throttle itself.)

5–30 %

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.

Guidelines for adjusting this parameter are provided in Section 5.

40–100 %

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.

Guidelines for setting Throttle Max are provided in Section 5.

On/Off

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.

On/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.
