How to Program
Function:
Enter the maximum reference. The maximum
reference is the highest value obtainable by summing
all references. The maximum reference unit matches
- The choice of configuration in par. 1-00
Configuration Mode:forSpeed closed-loop

3-41 Ramp 1 Ramp-up Time
Range:
0.01 - 3600.00 s

s
Function:
Enter the ramp-up time, i.e., the acceleration
time from 0 RPM to the rated motor speed n
M,N
(par. 1-25). Choose a ramp-up time such that
the output current does not exceed the current
limit in par. 4-18 during ramping. The value
0.00 corresponds to 0.01 sec. in speed mode.
See ramp-down time in par. 3-42.

s
Function:
Enter the ramp-down time, i.e., the de celeration
time from the rated motor speed n
M,N
(par. 1-2 5)
to 0 RPM. Choose a ramp-down time such that
no over-voltage 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. The value
0.00 corresponds to 0.01 s in speed mode.
See ramp- up time in par. 3-41.
