MC_GearInPos

This function block couples a slave axis to a specific position on a master axis. The speed ratio between the slave and master axes can be specified.

For an application example, refer to chapter Engaging the slave axis at a specific position of a master axis.

VAR_INPUT

Variable name	Data type	Description
Execute	BOOL	Start execution of the function block.
RatioNumerator	DINT	Numerator ratio master-slave (default value: 1)
RatioDenominator	DINT	Denominator ratio master-slave (default value: 1)
MasterSyncPosition	LREAL	Position of the master axis from which the master axis and slave axis are synchronous. If the master axis is a modulo axis, the MasterSyncPosition is interpreted as the modulo position.
SlaveSyncPosition	LREAL	Position of the slave axis from which the master axis and slave axis are synchronous. If the slave axis is a modulo axis, the SlaveSyncPosition is interpreted as the modulo position.
MasterStartDistance	LREAL	Distance covered by the master axis while the slave axis is synchronizing.
BufferMode	MC_BUFFER_MODE	Chronological sequence of the function block
RampInMode	E_RampInMode	Behavior during synchronization: eDirect: Synchronization takes place without a transition profile. This can lead to jumps in the setpoint curve. eProfileBased: Synchronization is performed with a profile-based transition profile based on the dynamic values RampInVelocity, RampInAcceleration, RampInDeceleration and RampInJerk. A continuous setpoint curve can be achieved. eMasterBased: Synchronization is performed with a master-based transition profile based on the parameters MasterSyncPosition, SlaveSyncPosition and MasterStartDistance. A continuous setpoint curve can be achieved.
RampInVelocity	LREAL	Speed for profile-based synchronization with RampInMode = eProfileBased
RampInAcceleration	LREAL	Acceleration for profile-based synchronization with RampInMode = eProfileBased
RampInDeceleration	LREAL	Deceleration for profile-based synchronization with RampInMode = eProfileBased
RampInJerk	LREAL	Jerk for profile-based synchronization with RampInMode = eProfileBased
Direction	MC_DIRECTION	Direction of synchronization, especially with modulo axes

VAR_OUTPUT

Variable name	Data type	Description
StartSync	BOOL	Slave axis synchronizes
InGear	BOOL	Slave axis is synchronous to the master axis
Busy	BOOL	Function block is active
Active	BOOL	Function block controls the axis
CommandAborted	BOOL	The function block was canceled by another command
Error	BOOL	An error has occurred in the function block
ErrorID	WORD	Error number
StartSync	BOOL	Slave axis synchronizes
