3.5.3 3-4* Ramp 1
Configure the ramp parameter, ramping times, for each of the two ramps (par. 3-4* and par. 3-5*).
3-41 Ramp 1 Ramp Up Time
Range:
10.00 s* [1.00 - 3600.00 s]
3-42 Ramp 1 Ramp Down Time
Range:
20.00 s* [1.00 - 3600.00 s]
3.5.4 3-5* Ramp 2
Choosing ramp parameters, see 3-4*.
3-51 Ramp 2 Ramp Up Time
Range:
10.00 s* [1.00 - 3600.00 s]
Function:
Enter the ramp-up time, i.e. the acceleration time from 0 RPM to par.1-25
Choose a ramp-up time such that the output current does not exceed the current limit in par.

Function:
Enter the ramp-down time, i.e. the deceleration time from par.1-25
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 Current Limit . See ramp-up time in par.3-41
