Voltage Throttle
Wire an external voltage throttle to an analog input as shown in Figure 11. In this example, the 0–5V
signal uses Analog 1 (Pot 1 at pin J1-13).

Wiring for 0–5V voltage
throttle.
e throttle voltage reference is from ground (GND, pin J1-16). Since throttle connections are not
made to the pot high (pin J1-18) and pot low (pin J1-6) inputs, the throttle fault protection is dierent
from 3-wire potentiometer throttles. Voltage throttles are congurable to recognize out-of-range
inputs using the available programming functions. e input will not become damaged from excessive
voltages (short to B+) on the throttle input (any of the analog inputs). However, when using 0–5V
throttles it is the responsibility of the vehicle manufacturer to provide throttle fault detection.
Other uses for the analog inputs
The throttle-pot inputs, Pot 1, 2, or 3, are configurable as speed limits, brake pedal, or other
potentiometer/voltage input. ese inputs can be programmed and wired as switches when referenced
to the +5V Out (pin J1-18). Analog inputs are programmable for multiple functions, including an
active low option.
Digital Inputs
All ve digital inputs are programmable for multiple functions; see Chapter 3, the IO Mapping for
examples and Chapter 4, Programmable Parameters, for complete descriptions. Described here are
some typical 1229 application’s wiring options.
Switches 1–4
Use switches 1–4 to trigger a specic function, such as forward, reverse, interlock, mode, li, lower,
etc. (see basic wiring diagrams in Figures 7–9). Wire these switch inputs from the KSI line aer the
keyswitch. ese programmable inputs can be set up to function as normally open (NO) or normally
closed (NC) switches.
Switch 5
Switch 5 is a high-speed digital input capable of accepting a signal from a motor speed sensor. e
frequency of this input is programmable, up to 30 kHz. is input is congurable as an active low
(switch to ground) input. To do so, connect it via a switch to ground (B-) as illustrated in Figure 7.
As with the other digital inputs, this input is programmable as normally open or normally closed.
