6.2 Initial commissioning
Step Adjustment for setpoint selection usin g
potentiometer (terminals 7, 8, 9 ) or
master voltage (terminals 7, 8 )
Further adjustment on additional use of a
dancer potentiometer (terminals 12, 13,
14)
1. Turn the trimmers ”U
max
”, ”U
min
”,
”Tänzer (Dancer)” to the left stop.
2. Set the setpoint potentiometer or master
voltage to zero.
3. Switch on the mains and close switch
”RFR”.
Adjustment of the minimum voltage
4. Increase the motor speed by turning
trimmer ”U
min
” clockwise until the
required minimum torque is set.
If zero is required as the minimum torque,
turn trimmer ”U
min
” back until the motor
just ceases to rotate to avoid a dead band
on the setpoint potentiometer in the
bottom range.
Adjustment of the maximum voltage
5. Set the setpoint potentiometer to
maximum or set master voltage to U
L
=
10 V.
6. Increase the motor torque by turning the
trimmer ”U
max
” clockwise until the
required maximum torque is set.
The setting for the minimum torque is to
be checked because the minimum and
maximum voltage can affect each other.
7. Set the setpoint potentiometer to the
middle position or set master voltage to
approx. 5 V.
8. Using the trimmer ”Tänzer (Dancer)”, set
the required effect of the dancer
potentiometer.
Position ”E” reduces the motor voltage,
Position ”A” inc reases the motor voltage.
9. . After the adjustment of the effect of the
dancer, repeat the adjustment of the
minimum voltage (see step 4) with the
dancer potentiometer in position ”E”.
10. Furthermore, repeat the calibration of the
maximum voltage (see steps 5 and 6) in
position ”A”.
11. Commissioning is complete.
