3-81 Quick Stop Ramp Time
Range: Function:
3 s
*
[0.01 - 3600.00 s] Enter the quick–stop ramp-down time, i.e. the deceleration time
from the rated motor speed to 0 RPM. Ensure that no resultant
over-voltage will arise in the inverter due to regenerative oper-
ation of the motor required to achieve the given ramp-down
time. Ensure also that the generated current required to achieve
the given ramp-down time does not exceed the current limit (set
in par. 4-18). Quick-stop is activated by means of a signal on a
selected digital input, or via the serial communication port.
