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
0V:Lowsignalduringtheo-timetper-td
5 V : High signal during pulse length td
Minimum value : td = 1.0 ms pulse length (-100% = reverse)
Averagesetting: td=1.5mspulsewidth(0%=neutralposition,motoro)
Maximum value : td = 2.0 ms pulse width (+ 100% = forward)
