3.3. input for set value
at use of external potentiometer (min. 10 kOhm) for set value the wiper has to be connected to pin17,
the others to pins 14 and 16. Pin 15 and 18 have to be connected and J 3 is to be removed. at use of
the internal set value via offset potentiometer pin 15 and 18 are left without connection and J3 is to be
set.
3.4. Timing
jumper J2 sets the timing of the hall sensor logic to reach an adaptation to several motor types. The
setting belongs to the direction of the phases. J2 changes the rotation sense of the electrical field.
3.5. Phasing
jumper J1 is for setting the phase shift of the signals of the hall sensors. The correct value is to
provide by the manufacturer of the motor (see datasheet of motor).
3.6. speed
range
the speed range is to be set by jumper J10 and J 11. One of four speed ranges is to be set. The best
result of speed control can be reached by setting the lowest acceptable range because of the
resolution.
4. commission
4.1. selection of power supply.
Any power supply can be used as long the minimal requirements listed below are fulfilled. We
recommend to remove the motor from the mechanical construction to avoid damage and danger by
uncontrolled movements of
Requirements to the power supply:
output voltage: min. 11 V DC max. 70 V DC
residual voltage: < 5 %
output current: 10 A nominal, 20 A peak
