Wiring Stepper Motor and Encoder
Risk of destruction!
To rule out the possibility of moving the devices connected out of the
control area, observe the following procedure when connecting the stepper
motor to the VariStep3 stepper motor driver:
1.
Configure the VariStep3 stepper motor driver for your device type (see
section
External Device
on page 53.
2.
Separate the stepper motor driver from the power supply.
3.
Connect the stepper motor of the VariFuel2 air/gas mixer or the throttle
to the stepper motor driver.
4.
Connect the VariStep3 stepper motor driver again to the power supply.
▸
Now, the stepper motor driver will initiate a reference run. The
device is ready for operation.
Assignment of the wire colors
Take the assignment of the wire colors of the wiring harness from the wiring
diagram enclosed with the wiring harness.
Wiring via the 11-pole plug on the stepper motor driver. The socket for the stepper motor and
encoder has 12 poles. The 11-pole plug must be plugged in at the far right. Pin 0 of the socket is
currently not in use and therefore locked. The VariStep3 stepper motor driver has been approved
for residential environments if the wiring of the stepper motor and encoder does have a length of
no more than 10 m (32').
