Powering up and Start-up
5.1.1 Leds
The MW500 contains three leds which indicate the inverter states. The Green Led indicates
the states "run" and "ready to run". The Yellow Led indicates the alarm state blinking the alarm
number code. The Red Led indicates the fault state blinking the fault number code. The folowing
table sumarises the MW500 Leds behavior.
Inverter States
Inverter ON, ready to run
Inverter ON, motor running
Inverter with alarm state
Inverter running with forced configuration via
DIP switch
Inverter in failure state (PWM disabled)
