12.1-11-7
Pr. 11-17–Pr. 11-20 limit the output current, the percentage base value is the drive’s rated
current (not the motor’s rated current). The minimum value between Pr. 11-17–11-20 and
Pr.06-12 becomes the current output limit. In acceleration and steady state operation, when the
output current reaches the limit, the ocA (over-current during acceleration) protection or
over-current stall prevention under steady-state operation acts. The output frequency drops, and
recovers when the output current is lower than the limit value.

IM: VF, VFPG, SVC / PM: PMSVC modes.
