UserDefinedStopMode defines which start values are used for the profile to stop the drive in user-defined stop.
User-defined stop is triggered when:
oDiagnostic messages with reaction BD2 occur.
oControllerEnable is switched off with ControllerEnableStopMode = UserDefinedStop / 0 .
Based on the start values, a profile defined via the ControllerStopDec and ControllerStopJerk parameter is triggered to stop the drive.
oAs a result, the current limit defined by UserCurrentLimit is disabled and the current limit defined by DriveStopCurrentLimit is enabled.
Depending on UserDefinedStopMode, the start values result from:
|
|
Start with actual values |
Start with reference values |
|---|---|---|
|
Position start value |
Position |
RefPosition |
|
Velocity start value |
Min(Velocity; RefVelocity) |
RefVelocity |
|
Acceleration start value |
0 |
RefAcceleration |
In Start with actual values mode, the smaller value of RefVelocity and Velocity is used for the velocity start value as long as RefVelocity and Velocity have the same sign. The velocity start value is set to zero if RefVelocity and Velocity have different signs. The acceleration start value is set to zero because the calculated value of the actual acceleration is too inaccurate.
In Start with reference values mode, the start values are used as in Start with actual values if TrackingDeviation exceeded the 10x value of TrackingDeviationLimit during profile start; otherwise, the drive behaves as in ControllerStop except that current limits with UserCurrentLimit are disabled during stopping. The drive is then available for MaxDrivePeakCurrent in order to move along the defined reference value profile when required.
The UserDefinedStopMode Start with actual values does not make sense for asynchronous motors without encoder (in open-loop V / f control mode, ControlMode = open-loop control / 1).
