Tip!
Set the synchronisation window in
C01079/1 higher than the amplitude of beat available
on the input signal:
[19-29] Example: Beat on the input signal
19.1.76.2 Quick stop
The quick stop function removes the drive from the interconnection and leads it to standstill.
• Quick stop is activated by setting bRfg0 to TRUE.
•
C01076/2 is used to set the delay time in [s] which refers as the acceleration/deceleration time
to the reference speed ( C00011 ).
• The angle setpoint created internally on the basis of the input signal nIn_v is saved.
• After bRfg0 is reset to FALSE, the angle setpoint is approached via the ramp function generator
again.
