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