3.1 Functional Description
The VariStep3 stepper motor driver drives the stepper motor of a gas mixer or throttle. This
stepper motor carries out position changes:
– The stepper motor adjusts the openings for the gas supply of the gas mixer and thereby
alters the composition of the gas-air mix.
– In the throttles the stepper motor changes the opening angle of the throttle and thereby
controls the supply of the gas-air mix.
Control can be manual or automatic. Manual adjustments can be made using buttons on the
stepper motor driver via a connected PC. In automatic mode, binary or analog input signals, such
as those provided by a master control, are analyzed. In addition, a connection via CAN bus and
Modbus is possible.
The stepper motor driver is configured using a connected PC. The software used for this purpose
is also used to display current system data and error messages.
3.2 Applications
The VariStep3 stepper motor driver can be used for the following MOTORTECH devices:
–
Gas mixer with stepper motor (e.g. VariFuel2)
–
ITB throttles with integrated stepper motor
–
TG throttle drives
If several devices which are to be controlled via the VariStep3 stepper motor driver are to be
used in one system, several stepper motor drivers are needed. An additional splitter is not
necessary.
Any use other than the one described in the operating manual shall be considered improper use
and will result in the voiding of all warranties.
