Swaping to lower size motor on Hitachi SJ300 VFD
Swaping to lower size motor on Hitachi SJ300 VFD
(OP)
What settings need to be changed to put 15HP motor instead of current 20HP on Hitachi's SJ300-150LFU. On Altivar VFD's its usually thermal and nominal currents, but on Sj300 manual I found only I0 in H parameters section without explanation.
Thanks
Thanks

Using a different size motor simply involves inserting the new nameplate info into the drive. You may want to evaluate the current and torque limits as well.
