TVD3.2bl 31
Speed control loop circuit
- variable components R9, C4
- amplification potentiometer P3 (X
P
)
- Take over the adjusted values when the device is exchanged
Standard set-up
- fixed R, C values: 220k
W,
22nF
- amplification potentiometer X
P
to 50%
- suits the majority of drives
Adjustment without measurement equipment
Connect the motor
command value = 0
Xp = 50%
R, C = basic values
Enable the drive
- Turn the potentiometer Xp clockwise until the axis begins to oscillate
- Turn the potentiometer Xp anti-clockwise until the oscillations disappear
- Turn the potentiometer Xp another 2 clicks anti-clockwise
Drive behaviour:
Amplification too low a mplification too high
long-wave oscillations 1 to 0.1Hz short oscillations 30 to 200Hz
large overshoots vibrates> during acceleration
overruns destination position vibrates> during braking and in position
Attention:
Drive connected to CNC/PLC controllers
For the maximum speed output from the controller, adjust the speed
command value to between 8V and 9V by means of the
potentiometer n
