Setting DRM Parameters
Context
According to an Australian standard, the inverters must comply with demand response modes (DRM).

|---|---|---|---|
DRM0 |
AI2–AI4 |
|
N/A |
DRM5 |
DI1 |
When S5 is turned on, the inverters do not output active power. |
When two or more DRM modes are used at the same time, the strictest requirement must be met. |
DRM6 |
DI2 |
When S6 is turned on, the output active power of the inverters does not exceed 50% of the rated power. |
|
DRM7 |
DI3 |
When S7 is turned on, the output active power of the inverters does not exceed 75% of the rated power, and the inverters consume the maximum reactive power. |
|
DRM8 |
DI4 |
When S8 is turned on, the output active power of inverters recovers. NOTE:
The inverters output active power based on the percentage set on the SmartLogger. |
Procedure
- Click Settings and ensure that Active Power Control Mode is set to No limit, Reactive Power Control Mode is set to No output, and connection port for Remote Shutdown is set to No.
- Set DRM parameters and click Submit.Figure 6-91 Setting DRM parameters
Parameter
Description
connection port Set the parameter to the AI port for DRM signals.
Startup current range If the current of the AI port is within the setting range, inverters are turned on. Otherwise, inverters are turned off.
Power Control Set DI parameters based on the DRM requirements.
