[Application dependant] Enter the ramp-down time, i.e., the deceleration time from the synchronous motor speed n
s
to 0
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

4.3 Basic Set-up Parameters
0-02 Motor Speed Unit
Option: Function:
This parameter cannot be adjusted while the motor is running.
The display showing depends on settings in par. 0-02
Motor Speed Unit and par. 0-03 Regional
Settings
. The default setting of par. 0-02 Motor Speed Unit and par. 0-03 Regional Settings depends
on which region of the world the adjustable frequency drive is supplied to, but can be re-program-
med as required.
NOTE!
Changing the
Motor Speed Unit will reset certain parameters to their initial value.
It is recommended to select the motor speed unit first before modifying other
parameters.
[0] RPM Selects display of motor speed variables and parameters (i.e. references, feedbacks and limits) in
terms of motor speed (RPM).
[1] * Hz Selects display of motor speed variables and parameters (i.e., references, feedbacks and limits) in
terms of output frequency to the motor (Hz).
0-50 LCP Copy
Option: Function:
[0] * No copy
[1] All to LCP Copies all parameters in all set-ups from the adjustable frequency drive memory to the LCP memory.
[2] All from LCP Copies all parameters in all set-ups from the LCP memory to the adjustable frequency drive memory.
[3] Size indep. of LCP 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.
[4] File from MCO to LCP
[5] File from LCP to MCO
[6] Data from DYN to LCP
[7] Data from LCP to DYN
This parameter cannot be adjusted while the motor is running.
