Startup current
Figure 18. Configuring the Startup Current
Figure 19. Start-up Retrial Function
ParkIRet - During motor start-up, dc current is injected to the motor for maximization of startup torque per ampere
rating. Users are able to use a higher level of dc current injection (ParkIRet scaling 255 = Motor Rated Amp * 0.866)
after two or more restarts. This is done to increase the chance of a successful start-up.
