17.1.72.2 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.
