Curtis AC F2-A, F4-A, F6-A Motor Controllers – FOS 4.5 – April 2022

Use the menus within the Controller Setup to configure the controller's inputs and output signals at

the low-voltage (35-pin connector) and the current and power at the UVW motor-phase and Battery

connections. The Inputs menu is where the analog inputs are setup and assigned. Following the Inputs

menu are the IO Assignments, Outputs (coil drivers), External Supplies, and Current Limits menus.

The Inputs parameter menu describes the optional usages for Analog 1, 6, 18, and 19. Based upon

these input's setup selection, the CIT and 1313 HHP Programmer app will open and/or hide a

different set of menu options. This is the context sensitivity aspect of the F-Series programmer menus.

The Analog Inputs 1, 6, 18, and 19 are selectable for use as Voltage, 3-Wire Potentiometer, 2-Wire

Potentiometer, or a Voltage with Supply input. Based upon the selection, the available (visible) setup

menus will differ. Review all the descriptions, below, to select the optimum option for the application.

• When configuring either Analog Input 1 or Analog Input 6 as a 3-Wire Potentiometer input,

• The same type of coupling is true with Analog Input 18 (paired with Analog 19) if its 3-Wire

The other Analog inputs, 2 – 5, 7 – 9, 14, and 31 are voltage inputs. In a typical application, as shown

in Figures 12 and 13, the drive motor temperature sensor is Analog 2. The motor encoder signals

are Analog 3 and 4.

PWM Input 10 (Switch 10) on the 35-pin controllers is configurable for either an analog frequency or

duty cycle input, besides its typical digital switch input. Figure 32 illustrates how this input's optional

signal chain operates.

Note that the analog input's usage as a digital (switch) input has a higher normalization range

(analog_input_x_high) maximum voltage limit of 30 volts. This allows their usage as digital (switch)

inputs without causing a voltage out-of-range fault. This does not change the indicated limits for an

input's analog measurement (usage) range.

the Programmer app will pair these inputs. The 3-wire input is the wiper and the other

becomes the 5V supply, labeled high. For example, Figure 13 has Input 1 as the 3-wire wiper,

while Input 6 is the supply (high). If Input 6 is set as the 3-wire (wiper), Input 1 will become

the 5V supply (high). In all cases, the actual potentiometer wiper connects to ground (pins 7 or

18) as illustrated in Figures 13 and 36.

Potentiometer is selected.
