INTRODUCTION
This equipment enables manually controlled power steering and automatic
centering. Manually controlled steering may use either a tacho-generator or, in a later
version, an inexpensive stepper motor fixed to the steering wheel. The automatic
centering operation requires a potentiometer mechanically fixed on the MDU (Motor
Drive Unit).
The MDU uses an inexpensive, robust and maintenance free three phases AC
induction motor.
Also, our patented system makes optional the adoption of an encoder mounted on
the steering motor shaft.
The on board CAN interface makes the communication exchange between our EPS
and other controllers placed on the truck rapid and simple, so potentially extending the
steering performance to steer equalization for traction speed, CAN management of a
wire guidance application and so on.
Configuration options, steering adjustment, measurement functions, and
toubleshooting operations are integrally supported by the ZAPI hand held
controller equipped with Eprom release number CKULTRA ZP3.01 or later.
Improved safety and operation are provided by having two microprocessor: the first
of them performs operations and a second one executes supervisor functions.
The microprocessors combined with the ZAPI hand held controller make servicing easy
and direct, reducing adjustment and troubleshooting time. Increased steering motor
performance and reduced noise levels are achieved by using MOSFET technology.
