This parameter cannot be adjusted while the motor is running.
Function:
Enter the ramp-down time, i.e., the deceleration time from the synchronous motor speed n
RPM. Choose a ramp-down time such that no overvoltage arises in the inverter due to regenerative
operation of the motor, and such that the generated current does not exceed the current limit set
in par. 4-18 Current Limit . The value 0.00 corresponds to 0.01 s in speed mode. See ramp-up time

NOTE!
Changing the Motor Speed Unit
It is recommended to select the motor speed unit first before modifying other
parameters.
Selects display of motor speed variables and parameters (i.e. references, feedbacks and limits) in
terms of motor speed (RPM).
Selects display of motor speed variables and parameters (i.e., references, feedbacks and limits) in
terms of output frequency to the motor (Hz).
Function:
Copies all parameters in all set-ups from the adjustable frequency drive memory to the LCP memory.
Copies all parameters in all set-ups from the LCP memory to the adjustable frequency drive memory.
Copy only the parameters that are independent of the motor size. The latter selection can be used
to program several adjustable frequency drives with the same function without disturbing motor
data.
