 VF, VFPG and SVC mode:
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.
 Calculation equation for the motor rated torque:
Motor rated torque =
ω(rad/s) value = Pr.05-03 (Pr.05-15);
 The control mode is based on 100% motor rated current except for these four modes:
IM: VF, VFPG, SVC / PM: PMSVC modes.
