If the POWER LED is off, it indicates no power. Check if the connection between the CMM-PD02 and the AC motor drive is normal.
What to do if the Delta DC Drives NET LED flashes orange?
If the NET LED flashes orange, it means that the CMM-PD02 fails to communicate with the AC motor drive. To solve this, switch off the power and check whether the CMM- PD02 is correctly installed and normally connected to the AC motor drive.
Why is the NET LED on my Delta VFD11AMS23ANSAA red?
A red light on the NET LED indicates that the CMM-PD02 is not connected to the PROFIBUS DP bus. To resolve this, connect the CMM-PD02 to the PROFIBUS DP bus.
What to do if the Delta VFD11AMS23ANSAA DC Drives NET LED flashes red?
If the NET LED flashes red, it signifies an invalid PROFIBUS communication address. To fix this, set the PROFIBUS address of the CMM-PD02 between 1–125 (decimal).
