184 Unidrive SP Regen Installation Guide

*SP2404 Power and current ratings
All Unidrive SP models are dual rated except for the SP2404 which only has a Heavy Duty rating. However, if the current limits in Pr 4.05 to Pr 4.07
are set to a maximum of 110% and the switching frequency is greater than 3kHz, then the drive can be used at a maximum continuous current higher
than the Heavy Duty rating. See the Normal Duty ratings in Table 10-1, Table 10-2 and Table 10-3. Normal Duty ratings exist for the SP2404 above
3kHz when the overload is reduced from the default value 165% in open loop or 175% in closed loop, to 110%.
If the current limits in Pr 4.05 to Pr 4.07 are set higher than 110% then the Heavy Duty current ratings are applicable.
