Technical Information
General Technical Specications
Automotive Control (AC) The H1 Automotive Control (H1 AC) is an
electric NFPE Control with an integrated
Microcontroller, installed on the pump.
The integrated Microcontroller enhanced
control performance with a exible,
congurable control scheme for an entire
single path propel transmission. With the
pre-installed application software and
easily changeable control parameters, it
is possible to tailor the vehicle’s driving
behavior to the individual requirements
of the customer.
The H1 AC Control oers the following
features and functions:

Driving Proles
• Four selectable system modes, selectable via switch.
• Independent curves and settings for forward and reverse (4 x 2 curves).
• Switch selectable between automotive and engine speed independent driving
modes.
• Engine speed independent drive modes for sweepers, snow blowers (non-automotive
mode).
– Load independent drive modes for o road applications (non-
automotive for rollers and forestry machines).
• Load independent swash plate control via pump swash plate angle sensor to achieve
EDC behavior
• Creep speed mode (slow shunting, digging operation, etc.)
• Constant speed mode (sweepers, snow-blowers, etc.)
• Integrated vehicle speed limiter function.
Advanced Control Functions
• Inch function without separate control valve.
• Integrated temperature sensor for:
– Hydraulic systems overheat protection.
– Low temperatures pump ow limitation.
– Compensation of oil viscosity changes if using (radial piston motors, etc.).
– Congurable engine anti stall protection.
– Engine over speed protection while inching.
Integrated Motor Controller
• Integrated electric motor control for:
– Proportional, variable PCOR or two position motor controls.
– Brake pressure defeat, depending on the FNR position
or the real vehicle driving direction.
– Initial breakaway motor torque override.
• Separate over speed protection for the hydro motor.
