5.6.2.7 Setting the Imax controller
Functionality
If ramp-up time is too short, the converter may display the alarm A501 which means the
output current is too high. The Imax controller reduces converter current if the output current
exceeds the maximum output current limit (r0067). This is achieved by reducing the
converter's output frequency or output voltage.
