Ramp Times:
Ramp up: Acceleration time. From 0 to nominal motor frequency (par.
C01.23).
Ramp down: Deceleration time. From nominal motor frequency (par.
C01.23) to 0.
Limitation:
Too short ramp up time can result in Torque limit warning (W12) and/or
DC over voltage warning (W7). Ramping is stopped when the frequency
converter has reached Torque limit motor mode (par. C04.16).
Too short ramp down time can result in Torque limit warning (W12)
and/or DC over voltage warning (W7). Ramping is stopped when the
frequency converter reaches the Torque limit generator mode (par.
C04.17) and/or the internal DC over voltage limit.

Function:
Enter ramp-up time from 0 Hz to rated motor speed (nM,N)
set in par. C01.25.
Choose a ramp-up time ensuring that output current does not exceed
current limit set in par. C04.18 during ramping.
* only for NV4,NV5
C03.41 Ramp 1 Ramp up Time
Default setting 3.00/
15.00S*
Range
[0.05 - 3600 s ]
●
Function:
Enter ramp down time from rated motor speed nM,N in
par. C01.25 to 0 Hz.
Choose a ramp down time that does not cause over-voltage in inverter
due to regenerative operation of motor. Furthermore, generated current
must not exceed current limit set in par. C04.18.
* only for NV4,NV5
C03.42 Ramp 1 Ramp Down Time
Default setting 3.00
/30.00S*
Range
[0.05 - 3600 s]
