Indicator Lights
The PCB is equipped with LED lights. LED1 to LED7.
Modbus LED lights
LED5 (red) and LED6 (green) are modbus LED lights. See page
for LED locations.
LED6 flashes fast when communicating.
LED5 has no function.
Motor LED lights
LED1 (red) and LED2 (green) are controlled by the circuit regulating the motor.
See page
for LED locations.
Start
When the frequency converter is connected to mains, the following pattern is shown:
1.
LED1 is turned off and LED2 is lit constantly => processor initialization
2.
After 5
–
10 seconds LED1 flashes a number of times to indicate the motor selected by the DIP
switches. This also indicates that the motor in questions has been initialized in the processor.
3.
At last LED1 turns off and LED2 starts flashing.
Operation
When there are no errors LED2 will be flashing. LED2 flashes when the motor is running and when it is
stopped. This indicates that everything is running normally.
Errors
If an error is detected, the frequency converter will stop the motor, turn on LED1 and turn off LED2.
HW Stop Function LED lights
LED7 (red) is controlled by the HW Stop function. When it flashes it is indicating that the switch is closed
and the HW Stop Function is not blocking the Frequency Converter.
If LED7 (red) is on constantly, it is indicating that the Frequency Converter has been blocked by the HW Stop
Function, and that it will not be able to continue until the Supply Voltage has been removed long enough
for the Frequency Converter to completely turn off and on again.
