mpiMotorDemandModeAnalogOffsetSet

Declaration

mpiMotorDemandModeAnalogOffsetSet(MPIMotor   motor,
                                  double     offset);

 

Required Header: stdmpi.h

Change History: Added in 04.00.

Description

mpiMotorDemandModeAnalogOffsetSet writes the motor’s output offset to the controller.  mpiMotorDemandModeAnalogOffsetSet is valid for a motor configured for the ANALOG demand mode. The motor offset demand is useful for open-loop +/- 10 volt control of analog drives.

Only SynqNet RMBs support the ANALOG demand mode. SynqNet drives supports TORQUE and VELOCITY mode, depending on the drive.

motor A handle to a motor object
offset An analog demand offset value. The valid range is -10 to +10 volts.
Return Values
MPIMessageOK
MPIMotorMessageMOTOR_INVALID

Sample Code

Example - Write the motor's analog demand offset.

double offset = .1;  /* volts */
MPIMotorDemandMode mode;

mpiMotorDemandModeGet(motor, &mode); 

if (mode == MPIMotorDemandModeANALOG) {
mpiMotorDemandModeAnalogOffsetSet(motor, offset);
}
