FB_SoEReadDcBusVoltage
With the FB_SoEReadDcBusVoltage function block the Dc-Bus voltage of the drive (S-0-0380) can be read.
Inputs
VAR_INPUT
sNetId : T_AmsNetId := '';
bExecute : BOOL;
tTimeout : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR
Name | Type | Description |
|---|---|---|
sNetId | T_AmsNetId | String, which contains the AMS Network ID of the PC (type: T_AmsNetId). |
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. |
Inputs/outputs
VAR_IN_OUT
Axis : NCTOPLC_AXIS_REF;(* reference to NC axis *)
END_VAR
Name | Type | Description |
|---|---|---|
Axis | Axis data structure of the type NCTOPLC_AXIS_REF |
Outputs
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
iAdsErrId : UINT;
iSercosErrId : UINT;
fDcBusVoltage : REAL;
dwAttribute : DWORD;
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 | Returns the ADS error code of the last executed command when the bError output is set. |
iSercosErrId | UINT | In the case of a set bError output returns the Sercos error of the last executed command. |
fDcBusVoltage | REAL | Returns the DC-Bus voltage (e.g. 294.0 corresponds to 294.0 V). |
dwAttribute | DWORD | Returns the attributes of the Sercos parameter. |
