7.1.2 Recommended ramp times as a function of SED2 output
SED2 output Frame size Ramp time
0.37 - 4 kW A - B 30 s
5.5 - 15 kW C 60 s
18.5 - 30 kW D 90 s
37 - 90 kW E - F 120 s
7.2 Application 2
A motor shall run at 4 fixed speeds.
− Control is accomplished via digital inputs
− Error message via relay output 1
− Indication of operation via relay output 2
Note: With the settings for this application, the assumption is made that the parameters use their default values
and that the connected motor has been commissioned with the standard parameters.
If several digital inputs are active at the same time, the setpoint will be added up.
The VSD is started when one of the inputs assumes the ON position.
