FAS_SetCommandPos
To set the command position value of the motor
Syntax
int FAS_SetCommandPos(
BYTE nPortNo,
BYTE iSlaveNo,
long lCmdPos
);
Parameters
nPortNo
Port number of relevant drive.
iSlaveNo
Slave number of relevant drive.
lCmdPos
Command position value to be set .
Return Value
FMM_OK : Command has been successfully performed.
FMM_NOT_OPEN : The drive has not been connected yet .
FMM_INVALID_PORT_NUM : There is no nPort in the connected ports .
FMM_INVALID_SLAVE_NUM : There is no drive of iSlaveNo in the relevant port .
Remarks
The user sets the position command (pulse output counter) value.
This function is generally used when the user sets the current position to coordinates
that customer wants.
Example
#include "FAS_EziMOTIONPlusR.h"
void funcClearPosition()
{
BYTE nPortNo = 1; // COMM Port Number
BYTE iSlaveNo = 0; // Slave No (0 ~ 15)
int nRtn;
// Try to connect
if (FAS_Connect(nPortNo, 115200) == FALSE)
{
// Connection failed.
// The port is not connected or the baudrate may be wrong.
return;
}
// Initialize Command Position and Actual Position values to 0.
nRtn = FAS_SetCommandPos(nPortNo, iSlaveNo, 0);
_ASSERT(nRtn == FMM_OK);
nRtn = FAS_SetActualPos(nPortNo, iSlaveNo, 0);
_ASSERT(nRtn == FMM_OK);
// Disconnect.
FAS_Close(nPortNo);
}
