Depending on the application, the HST-350 can be configured for different operating modes. You can set
the desired mode via the GUI (graphical user interface).

Control in the operating modes ADC and PPM
Currently there are several modes available for power control
a.)
‚Pedal control‘ (ADC) with analog input 0 - 5 V (voltage)
• Uses analog inputs PVS_1 and PVS_2 (see table [Pin 15 / 16]).
• This analog voltage can be generated with the potentiometer of an accelerator pedal, which must be
supplied either internally or externally with 5V.
• By default, the controller works with a lower diagnostic distance of 0.5V (0-0.5V) and an upper diagno-
stic distance of 0.5V (4.5V-5V).
• Thereby 0.5V corresponds to „0% power“ and 4.5V to „100% power“.

These data are parameterizable in the Basic-EEPROM.
b.) ‚PPM control‘ ( pulse-pause modulation)
- Uses input signals of the PPM input (see Table 3-2 [Pin 18 / 19], not shown in Fig. 2-1).
The PPM input signal must meet the following (servo PPM, pulse-pause modulation) requirements:
td = 1.0 ms to 2.0 ms :
pulse length (on-time)
fper = 50 Hz to 495 Hz :
duration of the PPM signal
0 V: Low signal during the off-time tper - td
5 V : High signal during pulse length td
Minimum value :
td = 1.0 ms pulse length (-100% = reverse)
Average setting :
td = 1.5 ms pulse width (0% = neutral position, motor off)
Maximum value :
td = 2.0 ms pulse width (+ 100% = forward)
