FB_SoEReadMotorTemperature_ByDriveRef
With the function block FB_SoEReadMotorTemperature_ByDriveRef the temperature of the motor (S-0-0383) can be read. If the motor does not contain a temperature sensor, this is 0.0, i.e. 0.0 °C.
Inputs
VAR_INPUT
stDriveRef : ST_DriveRef;
bExecute : BOOL;
tTimeout : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR
Name | Type | Description |
---|---|---|
stDriveRef | ST_DriveRef | Reference to the drive. The reference to the drive can be linked directly to the PLC in the System Manager. To do this, an instance of the structure ST_PlcDriveRef must be allocated and the NetID must be converted from the byte array into a string. (Type: ST_DriveRef) |
bExecute | BOOL | The function block is enabled via a positive edge at this input. |
tTimeout | TIME | Maximum time allowed for the execution of the function block. |
Outputs
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
iAdsErrId : UINT;
iSercosErrId : UINT;
dwAttribute : DWORD;
fMotorTemperature : REAL;
END_VAR
Name | Type | Description |
---|---|---|
bBusy | BOOL | This output is set when the function block is activated, and remains set until a feedback is received. |
bError | BOOL | This output is set after the bBusy output has been reset when an error occurs in the transmission of the command. |
iAdsErrId | UINT | In the case of a set bError output returns the ADS error code of the last executed command. |
iSercosErrId | UINT | In the case of a set bError output returns the Sercos error of the last executed command. |
dwAttribute | DWORD | Returns the attributes of the Sercos parameter. |
fMotorTemperature | REAL | Returns the motor temperature (e.g. 30.5 corresponds to 30.5 °C). If the motor does not contain a temperature sensor, this is 0.0, i.e. 0.0 °C. |
