Setting the motors
Setting the motor current
Attention:
Make sure to set the correct phase
current before you switch on the power supply.
Too high a current - even for a short time - can
damage the motor. If you do not need the full
torque of the motor, you can also set a slightly
lower current. This significantly reduces heat
generation. However, do not set less than 70%
of the rated current, otherwise the motor may
not run smoothly.
The phase current of the motor is adjusted with
the small blue control dial. Use a small
screwdriver for this. The regulator is very easy
to turn, do not use force. In the picture on the
right the regulator is now at 4.5A. You can set
any value, the adjustment is linear.
Setting the microsteps
The microsteps are set by means of the dip switch (the black box with the white levers in the
picture above right). Please set the switch as shown in the photo. This corresponds to 16
microsteps.
Connection of the motors
The motors are connected to the sockets X-axis to 4th axis. Where A+ and A- is one coil of
the motor and B+ B- is the other coil of the motor. If you do not have a data sheet at hand,
you can quickly test it with a multimeter. There must be continuity between the terminals of
one coil, the other two terminals must not have continuity. It does not matter which coil you
connect to A and B. It also does not matter how the coil is connected (i.e. A+ and A-
reversed). It is only important that between A+ and A- is one coil and between B+ and B- is
the other coil.
Use a shielded cable to connect the stepper motors and connect the shield to the ground of
the control cabinet.
Meaning of the LEDs
The two LEDs near the FI-Interface
indicate that the device is ready for
operation.The four LEDs in the middle of
the board indicate the control signals from
the PC for the 4 motors.
